Default key mapping: None
Sets or modifies an alias. See Aliases.
Default key mapping: None
Prompts for a regular expression and aligns the first occurrence of the specified regular expression in each line of the selected region.
For example, suppose you start with a region that looks like this:
private static final int STATE_VARIABLE = STATE_LAST + 1;
private static final int STATE_HERE_DOCUMENT = STATE_LAST + 2;
private static final int STATE_POD = STATE_LAST + 3;
private static final int STATE_REGEXP_DELIMITER = STATE_LAST + 4;
private static final int STATE_REGEXP = STATE_LAST + 5;
private static final int STATE_SUBST = STATE_LAST + 6;
If you specify "=" as the regular expression, alignStrings will reformat the
region like this:
private static final int STATE_VARIABLE = STATE_LAST + 1;
private static final int STATE_HERE_DOCUMENT = STATE_LAST + 2;
private static final int STATE_POD = STATE_LAST + 3;
private static final int STATE_REGEXP_DELIMITER = STATE_LAST + 4;
private static final int STATE_REGEXP = STATE_LAST + 5;
private static final int STATE_SUBST = STATE_LAST + 6;

Uses the default browser to view the file at the location of the caret.
For this command to work, you need to specify the properties browser and (optionally) browserOpts in your preferences file.
Default key mapping: Ctrl Shift B
This command is available in mail composition buffers when you're replying to a message. It adds all of the recipients of the original message to the "Cc:" header of your reply, just as if you had initiated the reply with messageReplyToGroup instead of messageReplyToSender.
Default key mapping: None
Centers the current function vertically in the edit window.
Default key mapping: None
Runs diff to show the unsaved changes to the current buffer (if any). In the resulting output buffer, you can use diffGotoFile, mapped by default to Enter, to jump to the location of a particular change.
Because it uses diff, this command will not work unless diff is installed and in your path, which is more likely to be the case on Unix than on Windows.
Default key mapping: None
Examines all the lines in the current buffer that start with "#include" and reports which included files can't be found in your include path (or in the current directory, if the filename is enclosed in quotes rather than in angle brackets). This command also recursively checks all the included files that it can find, and reports which (if any) of the files included by those files can't be found.
Default key mapping: None

Default key mapping: None
In directory buffers, copies to the kill ring (and
to the system clipboard) the full pathname of the file on the line containing
the caret.
Default key mapping: None
Copies the contents of the selected region (or the current line if no region is selected). For normal regions, the copied text is placed in the kill ring. If the selected region is a column, the text is saved but not placed in the kill ring; it can be retrieved with the command pasteColumn.
Default key mapping: Ctrl C
See also: copyAppend,

#else, #elif or #endif, finds the
matching expression. Otherwise, finds the match of the brace, parenthesis or
bracket at the location of the caret.
Default key mapping: Ctrl M in C++ mode
Executes an arbitrary CVS command. The CVS command, together with any required flags, must be supplied as an argument. The name of the file associated with the current buffer is automatically appended to the command line, unless the argument you supply begins with "-H". For example:
cvs status -v
or:
cvs -H admin
Default key mapping: None
See also: Version Control Systems
Adds the file associated with the current buffer to CVS. The file is not actually placed in the CVS repository until you use cvsCommit to make the change permanent.
Default key mapping: None
See also: Version Control Systems
Opens a checkin buffer in which you can compose a CVS checkin comment for the file associated with the current buffer.
When your comment is ready, you can use the command finish, mapped by default to Ctrl Enter in the checkin buffer, to complete the checkin operation.
The file associated with the current buffer must already have been registered with CVS using cvsAdd or the CVS "add" command.
Default key mapping: None
See also: Version Control Systems
Opens a diff output buffer showing the changes between the checked-in version of the file associated with the current buffer and your local copy.

Default key mapping: None
See also: Version Control Systems
Cycles through the most plausible possibilities for the indent size of the
current buffer (2, 4 and 8 spaces). The value that is currently in effect is
shown in the status bar.
If you use cycleIndentSize to set the indent size, j will try to
remember the setting the next time you open the same file.
Default key mapping: Alt I in most programming modes
If the last command to be executed was not paste or cyclePaste, cyclePaste does
exactly the same thing as paste.
If the last command to be executed was paste or cyclePaste, cyclePaste fetches
the next item from the kill ring and inserts it in
place of the text inserted by the last paste or cyclePaste.
What this means in practice is that you can invoke cyclePaste repeatedly to
cycle through the contents of the kill ring, stopping when you see that the
text you want has been inserted. If you can't find what you want and
would like to cancel the operation, use undo.
Default key mapping: Ctrl Shift V
Cycles through the most plausible possibilities for the tab width of the current buffer (2, 4 and 8 spaces). The value that is currently in effect is shown in the status bar.
This is intended to be a quick way to figure out the proper tab width to use when you've loaded a file for the first time and the indentation looks goofy. Just press Alt T repeatedly until things look right. Of course that may not happen; bear in mind that cycleTabWidth only considers the three most common possibilities.
If you use cycleTabWidth to set the tab width, j will try to remember the setting the next time you open the same file.
Default key mapping: Alt T
Executes an arbitrary darcs command. The darcs command, together with any required flags, must be supplied as an argument. The name of the file associated with the current buffer is automatically appended to the command line if the command is "whatsnew" or "w". The darcs command is run in the directory of the current editor.
Default key mapping: None
Base 64 decodes the selected region (or the line containing the caret if no region is selected). If the resulting output is text, it is displayed in a new buffer; otherwise, you are prompted for a filename and the output is saved in the specified file.
Default key mapping: None
Reloads the current buffer in its default mode.

In a Lisp shell, runs 'cl:describe' on the symbol under the caret.
Default key mapping: Ctrl Alt D in Lisp shell mode
Displays a list of the key bindings that are in effect in the current buffer.
Default key mapping: None
Displays information about the command mapped to a particular key or key combination.
Default key mapping: Alt K
Runs diff with the supplied arguments and presents the output in a diff output buffer.
When constructing the command line, you can use "%" as a dynamic alias for the file associated with the current buffer. For example:
diff -ub % ~/backup
If you don't explicitly specify any command line switches (e.g. "-ub", "-c",
"--normal"), j will run "diff -u".
If no arguments are provided, this command diffs the file associated with the current buffer against its patchMode backup file (if it exists).
Because it uses diff, this command will not work unless diff is installed and in your path, which is more likely to be the case on Unix than on Windows.
Default key mapping: None

Deletes the marked files, or, if no files are marked, deletes the file at the
current location of the caret.
Default key mapping: Delete in directory buffers
See also: Directory Buffers.
Prompts for a shell command and executes the specified command on all the marked files in the current directory buffer.
If no files are marked, the command is executed on the file at the current location of the caret.
If the command string contains '*', the command runs once, with the list of marked files in place of the '*'. The order of the list is the order of appearance in the directory buffer.
If the command string does not contain '*', the command runs separately for each file, with the file name added at the end of the command string.
In all cases, the command is executed in the current directory (the directory displayed in the directory buffer).
Default key mapping: '!' in directory buffers
See also: Directory Buffers.
Changes to the next directory in the history list for the current directory buffer.
Default key mapping: 'f' in directory buffers
See also: Directory Buffers.
Copies the remote file at the current location of the caret to a specified
destination on the local machine. You can specify either a filename or a
directory as the destination.
Default key mapping: G in remote directory buffers
See also: Directory Buffers.
If the caret is to the right of the first character of the filename on the
current line, moves the caret to the first character of the filename.
Otherwise, moves the caret to the beginning of the line.

Prompts for a shell command and then executes that command, using the selected
region as input. The contents of the selected region are replaced by the
output of the command. If an error occurs, you can use
undo to restore the previous contents.
doShellCommandOnRegion is an experimental command, not enabled by
default. On Windows, you need to have the
Cygwin tools installed, and
sh.exe must be in your path.
Default key mapping: None

Drops a numbered bookmark at the location of the caret in the current buffer. By
default, dropBookmark is mapped to the ten keystrokes Alt 0 through Alt
9, and gotoBookmark is mapped by default to the ten keystrokes Ctrl 0
through Ctrl 9. When you drop a bookmark with Alt n, you can return to it with
Ctrl n. It's possible to unmap these keystrokes or map other commands to them,
but the current implementation of dropBookmark and gotoBookmark
only works with these key mappings.
You can still return to a bookmark even if the buffer it refers to has been
closed (in that case the buffer will be re-opened in the current frame), but
bookmarks are not retained from one session to the next.
Default key mapping: Alt 0 through Alt 9 (bookmarks 0-9)
See also: gotoBookmark,
selectToMarker,
dropTemporaryMarker
Drops a temporary marker at the location of the caret in the current buffer.
You can use gotoTemporaryMarker, mapped by default to Ctrl \, to return to the location of the temporary marker.
This command recycles the same temporary marker for each subsequent use, so you can only have one temporary marker at a time.
Default key mapping: Alt \
See also: dropBookmark,
gotoTemporaryMarker,
selectToTemporaryMarker
Opens the preferences file for editing.
Default key mapping: None
Prompts for a register name and opens a buffer so you can edit the contents of the specified register.

Inserts '>' and, if the property
autoIndent is true,
re-indents the current line according to context.
Default key mapping: '>' in HTML and XML modes
Inserts '}' and re-indents the current line according to context. If
the property autoNewline
is true, also inserts a line separator
and moves the caret to the appropriate column on the new line.
Default key mapping: '}' in Java, JavaScript, C and C++ modes
See also: electricOpenBrace
Inserts ')' and evaluates the sexp in the lisp shell if complete.
You can add this to your init.lisp with:
(map-key-for-mode ")" "electricCloseParen" "Lisp Shell")
Inserts a colon at the current location of the caret and re-indents the current
line according to context. If the property
autoNewline is true,
also inserts a line separator and moves the caret to the appropriate column on
the new line.
Default key mapping: ':' in Java mode
Inserts '{' and re-indents the current line according to context. If
the property autoNewline
is true, also inserts a line separator
and moves the caret to the appropriate column on the new line.
Default key mapping: '{' in Java, JavaScript, C and C++ modes
See also: electricCloseBrace
Inserts a '#' character at the current location of the caret. If the line
contains only whitespace, the '#' will be forced into the first column.
Default key mapping: '#' in C and C++ modes
Inserts a pair of '"' characters at the current location of the caret and
places the caret between them. If the cursor is on a '"' character, a newline
will be inserted and the caret will be indented according to the context.
Default key mapping: Ctrl " in Lisp mode
Inserts a semicolon at the current location of the caret and re-indents the
current line according to context. If the property autoNewline is
true, also inserts a line separator and moves the caret to the
appropriate column on the new line.
Default key mapping: ';' in Java, JavaScript, C and C++ modes
Inserts '*' at the current location of the caret and, if the current line is
otherwise blank, re-indents the line according to context.
Default key mapping: '*' in Java, JavaScript, C and C++ modes
Moves the caret to the end of the current line.
If the preference extendEnd is true, invoking end repeatedly in quick sequence triggers special behavior after the caret reaches the end of the current line: the caret is first moved to the bottom of the edit window, and then to the end of the buffer. There is a one-second timeout on this operation, meaning that if one second elapses between invocations of end, the second invocation is viewed as an independent event rather than a repetition of the first, and the special behavior is not triggered.
Default key mapping: End

Escapes from the last operation.
More specifically, closes the most recently visited transient buffer (and possibly unsplits the window). Transient buffers include help buffers, list occurrencess buffers, and compilation buffers.
If no transient buffer is currently displayed, clears the selection (if any) in the current buffer.
Otherwise, cancels any background process associated with the current buffer.
Each invocation of escape does at most one thing.
Default key mapping: Escape
Executes an editor command by name. The "Command:" textfield in the location bar supports both history (using the up and down arrow keys) and completion (using Tab and Shift Tab).
Some commands (for example, insertString, help, jdkHelp, and source) require or accept an argument (which in the current implementation is always a string). Such commands can be entered like this:
insertString this is a test
or like this:
insertString("this is a test")
Default key mapping: Alt x
Replaces the text to the left of the caret with a word in the current buffer for
which that text is a prefix.
The expand command takes the sequence of characters you've just typed (more
precisely, the sequence of characters that are legal in a Java identifier,
beginning immediately to the left of the caret), looks through the entire
buffer for words (i.e. legal Java identifiers) that have the sequence in
question as a prefix, and replaces the sequence of characters with the first
match it finds.
If you don't like that particular replacement, you can hit Alt Space (or Alt /) again (and again and again) to cycle through all the possible replacements. If you don't like any of the replacements, you can use undo, mapped by default to Ctrl Z, or escape, mapped by default to Escape, at any point, and get back where you started.
In the header area of a mail composition buffer, expand looks for completions in the global address book, rather than in the text of the buffer, so you can use it to auto-complete mail addresses.
This functionality is also available in all of j's textfields (both in dialog boxes and in the location bar), with the same default key mappings. In a textfield, the expansion text is taken from the current buffer, and the expansion can be cancelled by pressing Escape.
Default key mapping: Alt Space (except on Windows), Alt /
Prompts for a pattern and finds the next occurrence of the specified pattern in the current buffer.
The search is case-insensitive if the "Ignore case" checkbox is checked.
If the "Whole words only" checkbox is checked, a match is returned only if it is both preceded and followed by a non-word character (i.e. a character not legal in an identifier, based on the mode of the buffer).
If the "Regular expression" checkbox is checked, the pattern is interpreted as a regular expression rather than as a simple string.
If the "Multiline pattern" checkbox is checked, the regular expression can contain newline characters ("\n"). Because of the way j handles things internally, a single "\n" should be used to match a newline even if the file being edited uses "\r\n" or "\r" as its line separator string. (The "Multiline pattern" feature is experimental and is not enabled by default.)
If the "List occurrences" checkbox is checked, all lines in the current buffer that match the specified pattern are listed.
If the "Search from start of document" checkbox is checked, the search begins at the start of the document. Otherwise, the search begins at the current location of the caret.
Default key mapping: Ctrl F, Alt F3
Note: If you set
useIncrementalFind to true
in your preferences file,
incrementalFind will be mapped by
default to Ctrl F.
Finds the first occurrence in the current buffer of the word at the current location of the caret.
The search is case-sensitive and is carried out as if the "whole words only" option was specified.
Default key mapping: Ctrl Alt Up
See also: findNextWord,
findPrevWord
Prompts for a pattern and a file specification and generates a list of all occurrences of the specified pattern in files matching the file specification.
Several file specifications can be supplied at once, separated by semicolons. If the full path is not given in a file specification, the current directory or the directory last specified by a full path is used.
For example, if the file specification is *.c;/usr/src/emacs-20.3/src/*.c;*.h,
the search will examine .c files in the current directory and
.c and .h files in /usr/src/emacs-20.3/src.
If the "Default excludes" checkbox is checked, the search will ignore files that match the filenameCompletionsExcludePattern.
The search is case-insensitive if the "Ignore case" checkbox is checked.
When the "Whole words only" checkbox is checked, a match is returned only if it is both preceded and followed by a non-word character (i.e. a character not legal in an identifier in the specified mode).
If the "Regular expression" checkbox is checked, the pattern is interpreted as a regular expression rather than as a simple string.
If the "Include subdirectories" checkbox is checked, the search examines files
in any subdirectories of directories in the file specification. For example,
if the file specification is /usr/src/linux/*.c, the search will
examine .c files in /usr/src/linux and all of its
subdirectories.
If the "Search files in memory" checkbox is checked, if a file matching the file specification is currently loaded in a buffer, the contents of the buffer will be searched rather than the file as last saved on disk, so unsaved changes to the buffer will be taken into account.
You can use the command escape, mapped by default to Escape, to cancel a search in progress.
Default key mapping: Ctrl Shift F, F6
See also: listFiles
Finds the match of the brace, parenthesis or bracket at the location of the
caret.
Default key mapping: Ctrl M

The search is case-sensitive and is carried out as if the "whole words only" option was specified.
Default key mapping: Alt Up
See also: findFirstOccurrence,
findNextWord
Prompts for a tag (generally speaking, a tag is a function name) and moves the caret to the definition of the specified function. The current location of the caret is first saved on the marker stack as a temporary bookmark, so you can use popPosition, mapped by default to Shift F5, to get back where you came from.
Default key mapping: Ctrl T
See also: findTagAtDot,
findTagAtDotOtherWindow,
mouseFindTag
Jumps to the definition of the function at the current location of the caret. The current location of the caret is first saved on the marker stack as a temporary bookmark, so you can use popPosition, mapped by default to Shift F5, to get back where you came from.

Returns to a previously dropped numbered bookmark. By default,
dropBookmark is mapped to the ten keystrokes Alt 0 through Alt 9, and
gotoBookmark is mapped by default to the ten keystrokes Ctrl 0 through
Ctrl 9. When you drop a bookmark with Alt n, you can return to it with Ctrl n.
It's possible to unmap these keystrokes or map other commands to them, but the
current implementation of dropBookmark and gotoBookmark only
works with these key mappings.
You can still return to a bookmark even if the buffer it refers to has been closed (in that case the buffer will be re-opened in the current frame), but bookmarks are not retained from one session to the next.
Default key mapping: Ctrl 0 through Ctrl 9 (bookmarks 0-9)

For Windows, you'll need to use double backslashes, like this:
docPath=c:\\j\\doc
If you use
executeCommand to invoke help, you can
specify the command you want help on at the same time:
help executeCommand
or
help("executeCommand")
Default key mapping: F1
See also: executeCommand
Moves the caret to the beginning of the text on the current line, if the caret is to the right of that location to begin with. If the caret is already at the beginning of the text on the current line or in the whitespace to the left of the text, home moves the caret to column 1 on the same line.
If the preference extendHome is true, invoking home repeatedly in quick sequence triggers special behavior after the caret reaches column 1 on the current line: the caret is then moved to the top left corner of the edit window, and then to the beginning of the buffer. There is a one-second timeout on this operation, meaning that if one second elapses between invocations of home, the second invocation is viewed as an independent event rather than a repetition of the first, and the special behavior is not triggered.
extendHome is false by default.
Default key mapping: Home
See also: end
Inserts an HTML bold tag ("<B>") before the selected text (or before the location of
the caret, if there's no selection) and an HTML end tag ("</B>") after the selected
text (or after the location of the caret).
The case of the inserted tags is controlled by the property HtmlMode.upperCaseTagNames,
which is true by default.
Default key mapping: Ctrl B in HTML mode
See also: htmlInsertTag
Inserts '=' at the current location of the caret.
In HTML mode, if the property
attributesRequireQuotes
is true, and if the '=' immediately follows an attribute name, and if the
character following the '=' is either whitespace or '>', this command inserts
a pair of double quotation marks after the '=' and positions the caret between
the quotation marks.
The effect of this is to make it possible to enclose attribute values in quotation marks without having to type the quotation marks themselves.
Default key mapping: '=' in HTML mode
See also: xmlElectricEquals
Inserts an empty HTML end tag, with the caret positioned after the opening "</".
Default key mapping: Ctrl Shift .
Finds the match to the HTML tag at the location of the caret. Nested tags are
handled correctly.
Default key mapping: Ctrl M in HTML mode
Inserts the HTML end tag corresponding to the last HTML start tag before the
location of the caret. Nested tags are not currently supported.
Default key mapping: Ctrl E in HTML mode
Inserts an HTML start tag and (if appropriate) the corresponding end tag,
enclosing the current selection. If no selection is marked, the start and end
tags will enclose the word at the current location of the caret, if any.
If the property HtmlMode.fixCase
is true, the tag name will be converted to the preferred case (as specified by
HtmlMode.upperCaseTagNames
when it is inserted in the buffer.
J will normally insert an end tag unless it is forbidden. You can customize this
behavior by supply a tag customization file; see HtmlMode.tags.
Default key mapping: Ctrl Shift , (Ctrl Shift comma) in HTML mode
Inserts an empty HTML start tag, with the caret positioned after the opening angle bracket.
Default key mapping: None
Displays the request and response headers for the current HTTP buffer.
Default key mapping: None
Displays the Common Lisp HyperSpec documentation for the symbol at the current location of the caret.
The documentation is displayed in another window, splitting the current window if necessary. This transient window can be dismissed using escape, mapped by default to Escape.
You can also invoke the hyperspec command with Alt X, giving the symbol name as an argument (e.g. Alt X, "hyperspec mapcar", or Alt X, "hs mapcar").
The Common Lisp HyperSpec is available here:
http://www.lispworks.com/reference/HyperSpec/index.html
For this command to work, you may need to add a line to your preferences file specifying the location of the HyperSpec root directory on your system:
clhsRoot = /usr/share/doc/hyperspec
Default key mapping: Alt F1 in Lisp mode
Abbreviations: hs, clhs
See also: clhsRoot
Lists all occurrences of the identifier at the location of the caret, both in the current buffer and in any files referenced by a "#include" directive in the current buffer, in the order in which they occur.

preferences file:
inbox = pop://peter@annie
or for IMAP:
inbox = {peter@annie}inbox
Default key mapping: None
Prompts for input and finds the string entered, as it is typed in.
The search is case-insensitive unless (or until) the pattern contains at least
one upper case character.
In the incremental find textfield, any key combination mapped to
incrementalFind or findNext can be used to search
for the next occurrence of the current pattern, and any key combination mapped
to findPrev can be used to search for the previous occurrence of
the pattern. (By default, findNext is mapped to F3 and Ctrl G, and
findPrev is mapped to Shift F3 and Ctrl H.)
Ctrl W can be used to copy text from the buffer into the search pattern. Ctrl W copies the text from the buffer starting at the current location of the caret up until the end of the current word (or the end of the next word, if the caret is already at the end of the current word).
Ctrl P and Ctrl N can be used to navigate through the history list of previously used search patterns.
If you invoke incrementalFind and then realize you'd rather use find instead, you can get there by simply pressing Enter (as long as the incremental find textfield is empty).
Default key mapping: None
Note: If you set
useIncrementalFind to true
in your preferences file,
incrementalFind will be mapped by default to
Ctrl F.

Inserts an opening brace followed by a closing brace, indented appropriately,
leaving the caret positioned between them.
Default key mapping: Ctrl Shift [ in Java, JavaScript, C and C++ modes
Inserts the character that corresponds to the specified byte in the default
encoding at the current location of the caret. The byte must be specified as a
decimal, hexadecimal or octal number. A leading zero denotes an octal number; a
leading "0x" or "0X" denotes a hexidecimal number; otherwise the number is
assumed to be decimal.
Default key mapping: None
Inserts the specified Unicode character at the current location of the caret.
The character must be specified as a decimal, hexidecimal or octal number. A
leading zero denotes an octal number; a leading "0x" or "0X" denotes a
hexidecimal number; otherwise the number is assumed to be decimal.
Default key mapping: None
Inserts the next key combination you type (which can be a single key like Enter
or Backspace, or a combination like Ctrl Alt S) as a string (like "Enter" or
"Backspace" or "Ctrl Alt S") at the location of the caret in the current
buffer. The action mapped to the key combination in question (if any) is not
performed. Useful for editing a custom key map. The inserted text is guaranteed
(well, not guaranteed, exactly, but extremely likely) to be in a format
recognizable by j's key map parser.
Default key mapping: None
If a region is selected, inserts parentheses around the selected region.
Otherwise, inserts an opening parenthesis followed by a closing parenthesis,
leaving the caret positioned between them.
If parensRequireSpaces is
true, single space characters are added after the opening parenthesis
and before the closing parenthesis.
Default key mapping: Ctrl Shift ( in Java, JavaScript, C, C++, Lisp and Perl modes
See also: movePastCloseAndReindent

clearRegister,
editRegister,
listRegisters.
saveToRegister
Requires a string argument. The supplied string argument is inserted in the current buffer at the location of the caret. Can be invoked using executeCommand or mapped to a key combination in a global or mode-specific key map.
For example:
insertString("e.printStackTrace( );")
Default key mapping: None
See also: executeCommand
If useTabs is true for the current buffer, inserts a
tab character at the location of the caret, otherwise inserts the appropriate
number of spaces, based on the buffer's indentSize.
Buffer-specific settings such as useTabs and
indentSize may be inspected and modified in the Properties dialog
(see properties).
Default key mapping: Ctrl Tab in Java and HTML modes
Invokes j's built-in Java debugger, or, if the debugger is already running, ensures that the debugger transcript buffer is visible.
If an argument is supplied, it is passed as a command to the running instance of the debugger. For example:
jdb restart
It is an error to use this command with an argument unless the debugger has already been started.
Default key mapping: None
See also: The Java Debugger,
Debugger Commands
Displays the JDK HTML help file corresponding to the class name at the location of the caret or mouse click.
The help file is displayed in another window, splitting the current window if necessary. The help buffer can subsequently be dismissed using escape, mapped by default to Escape.
For this to work, you need to add a line to your preferences file specifying the location of the JDK documentation:
jdkDocPath=/home/peter/sun/jdk1.3/docs
Default key mapping: Alt F1 in Java mode
See also: jdkDocPath
Runs Armed Bear Lisp embedded in the running instance of j, with interaction in a Lisp shell buffer.
Using this command to run Lisp lets you use the resulting Lisp shell to interact with the running instance of j.
If you don't need to interact with the running instance of j, you should use the lisp command instead of this one. The lisp command runs Lisp as a separate process, making it less likely that ensuing anomalies will have a detrimental impact on your editor session.
Default key mapping: None
See also: lisp
Measures the performance of the underlying Java runtime system (which is, of course, dependent on the performance of the underlying hardware). The result is displayed in the status bar.
The first measurement in a given session may be wildly inaccurate, since some just-in-time compilers wait to compile a method until the second time it is called.
Default key mapping: None
Prompts for a column number and moves the caret to the specified column.
The column number can be a simple number ("123"), an arithmetic expression ("100+23"), or a positive or negative offset from the current location ("+7", "-12").
Default key mapping: None
Prompts for a line number and moves the caret to the beginning of the specified line.
The line number can be a simple number ("123"), an arithmetic expression ("100+23"), or a positive or negative offset from the current location ("+7", "-12").
Default key mapping: Ctrl J
Prompts for an absolute offset (the number of characters from the start of the buffer) and moves the caret to the specified location.
The offset can be a simple number ("123"), an arithmetic expression ("100+23"), or a positive or negative offset from the current location ("+7", "-12").
Default key mapping: None

Default key mapping: Ctrl Shift W
Copies the text from the location of the caret to the end of the current line to
the kill ring and then deletes that text. If the
text to be deleted is nothing but whitespace, or if the caret is already at the
end of the line, the following line separator is copied to the kill ring and
deleted too.
Default key mapping: Ctrl K
Deletes the selected region (or the current line if no region is selected). For normal regions, the deleted text is placed in the kill ring. If the selected region is a column, the deleted text is saved but not placed in the kill ring; it can be retrieved with the command pasteColumn.
Default key mapping: Ctrl X

Default key mapping: Ctrl L, Ctrl F3
Lists all occurrences in the current buffer of the selected text (if any) or of the word at the current location of the caret.
If text is selected on the current line, the selected text is used as the pattern for the search, and the search is carried out as if the "whole words only" option was not specified.
If there is no selection on the current line, the word at the current location of the caret is used as the pattern, and the search is carried out as if the "whole words only" option was specified.
The search is case-sensitive (in both cases).
Multi-line selections are not supported.

Default key mapping: Mouse-1
See also: mouseSelect
If a selection is marked, the contents of the selected region are copied to the kill ring, and the region is deselected. Then the copied text is inserted at the location of the mouse click.
If no selection is marked, mousePaste is equivalent to paste at the location of the mouse click.
If the text to be inserted ends with a line separator, it is inserted above the line where the mouse click occurred, as if the mouse click were in the first column of the line, even if that is not the case. The intention behind this is to make it easy to paste whole lines of text (or blocks of lines), without having to click exactly at the beginning of the line. If possible, the indentation of the inserted lines is corrected to match their new context.

characters from the start of the buffer).
Default key mapping: None
See also: jumpToOffset
Sets focus to the edit control in the location bar of the current window,
where you can enter a filename and press Enter to activate the corresponding
buffer, if it exists, or else create and activate a new buffer for the
specified file.
If the specified file is not found in the current directory, j will look for it
first in the include path (if it's a
.h file) and then in the source path.
You can define include and source paths in your preferences file.
If j can't find the file you specify, you will be asked if you want to create
it.
The edit control supports both history (using the up and down arrow keys) and
completion (using Tab and Shift Tab).
In addition to normal text files, you can open a directory, a .zip or .gz file,
or a URL (like http://armedbear.org).
If you press Enter with no text in the edit control, you will get a directory
buffer on the current directory.
Default key mapping: Ctrl O
See also: Directory Buffers.

Moves the caret up one full screen in the other window in the same frame.
Default key mapping: Alt Page Up
The contents of the system clipboard (if any) are appended to the kill ring, and then the last item from the kill ring (which will be the contents of the system clipboard, if anything was there) is inserted at the current location of the caret.
If a block is marked, the inserted text replaces the marked block.
By default, if the text to be inserted ends with a line separator, it is inserted above the line containing the caret, as if the caret were in the first column of the line, even if that is not the case. The intention behind this is to make it easy to cut and paste whole lines of text (or blocks of lines), without having to move the caret to the beginning of the line. If possible, the indentation of the inserted lines is corrected to match their new context.
You can disable this behavior by setting the property autoPasteLines to false. If autoPasteLines is false, the inserted text is always placed at the exact location of the caret.

Changes the first number in each line of the selected region so that the it is one more than the first number in the preceding line. By default, the smallest value in the entire region is used as the value for the first line. The order of the lines is not changed. Only the first number in each line is considered, and lines that don't contain a number at all are ignored.
For example, suppose you start with a region that looks like this:
private static final int DEFUN = 52;
private static final int DEFVAR = 6;
private static final int DO = 17;
private static final int DOLIST = 81; // Not 82!
private static final int IF = 9;
private static final int LAMBDA = 1;
private static final int LET = 3;
When invoked with no arguments, renumberRegions starts by looking at the first
number in each line of the region to find the smallest value (which in this
case is 1). The first number in the first line of the region (52) is replaced
with this value (1), and the first number in each subsequent line is changed so
that it is one more than the first number on the preceding line. So the region
ends up looking like this:
private static final int DEFUN = 1;
private static final int DEFVAR = 2;
private static final int DO = 3;
private static final int DOLIST = 4; // Not 82!
private static final int IF = 5;
private static final int LAMBDA = 6;
private static final int LET = 7;
You can also explicitly specify what number to start with by providing a
numeric argument with the command. For example, if you do Alt X,
"renumberRegion 100", the region ends up looking like this:
private static final int DEFUN = 100;
private static final int DEFVAR = 101;
private static final int DO = 102;
private static final int DOLIST = 103; // Not 82!
private static final int IF = 104;
private static final int LAMBDA = 105;
private static final int LET = 106;
Default key mapping: None
See also: sortLines
Replaces one or more occurrences of one pattern with another.
If the "Ignore case" checkbox is checked, j tries, paradoxically, to preserve case, if possible, when it makes a replacement. More precisely, if the pattern is all upper case, j will make the replacement all upper case, and if the pattern begins with an upper case letter, j will make the replacement begin with an upper case letter. For example, if the pattern is "javaFormatter" and the replacement is "cppFormatter", "JAVAFORMATTER" will become "CPPFORMATTER", and "JavaFormatter" will become "CppFormatter". These are the only two situations in which the replacement string is altered to preserve case. Upper-case letters in the replacement string are NEVER converted to lower case. This may seem strange, but in practice, chances are good that this is the behavior you want.
If the "Whole words only" checkbox is checked, occurrences of the pattern will be replaced only if they are delimited by characters that cannot appear in a Java identifier. Generally speaking, Java identifiers can contain letters, digits, and the characters '$' and '_'.
If the "Regular expressions" checkbox is checked, the pattern will be interpreted as a regular expression rather than as a literal string. In addition, the replacement string can refer to all or part of what is matched by the pattern. "\&" in the replacement string will be replaced with the entire string that matched the pattern. "\n", where n is a digit from 1 to 9, will be replaced by whatever matched the nth parenthesized grouping in the pattern. See Regular Expressions.
For example, if you specify this pattern:
foo\((.*), (.*)\)
and this replacement:
foo(\2, \1)
the effect would be to reverse the order of the arguments in every call to the
function foo. Note that you need to escape the literal parentheses in the
pattern, but not in the replacement.
If the "Multiline pattern" checkbox is checked, both the regular expression and the replacement can contain newline characters ("\n"). Because of the way j handles things internally, a single "\n" should be used to match a newline even if the file being edited uses "\r\n" or "\r" as its line separator string. (The "Multiline pattern" feature is experimental and is not enabled by default.)
If the "Restrict changes to selected text" checkbox is checked, only those occurrences of the pattern that fall within the current selection are replaced. Otherwise, if a block is marked, replacements are carried out starting at the beginning of the marked block.
If the "Confirm changes" checkbox is checked, you will be prompted to confirm
each replacement.
Default key mapping: Ctrl R
Replaces one or more occurrences of one pattern with another in multiple files. If a file matching the file specification is already loaded in a buffer, the operation is performed on the contents of the buffer rather than the file as last saved on disk, so unsaved changes to the buffer are never lost. Files that were not previously loaded are saved automatically if any replacements are made. Buffers created specifically for the replace in files operation are deleted when they are no longer needed.
Several file specifications can be supplied at once, separated by semicolons. If the full path is not given in a file specification, the current directory or the directory last specified by a full path is used.
For example, if the file specification is *.c;/usr/src/emacs-20.3/src/*.c;*.h,
the search will examine .c files in the current directory and
.c and .h files in /usr/src/emacs-20.3/src.
If the "Ignore case" checkbox is checked, j tries, paradoxically, to preserve case, if possible, when it makes a replacement. More precisely, if the pattern is all upper case, j will make the replacement all upper case, and if the pattern begins with an upper case letter, j will make the replacement begin with an upper case letter. For example, if the pattern is "javaFormatter" and the replacement is "cppFormatter", "JAVAFORMATTER" will become "CPPFORMATTER", and "JavaFormatter" will become "CppFormatter". These are the only two situations in which the replacement string is altered to preserve case. Upper-case letters in the replacement string are NEVER converted to lower case.

Sets the character encoding to be used when the current buffer is saved. The encoding name that you specify (e.g. "ISO-8859-1", "UTF-8", "UTF-16", "UnicodeBig", etc.) must be supported by the version of Java that you're using; the string is not case-sensitive.
Java recognizes both canonical names and aliases for a variety of encodings, and to make things more interesting, there are significant variations in this area among the different versions of Java. More information from the perspective of Java 1.4 is available here:

If a multi-line region is selected, or if the property tabAlwaysIndent is true, this command simply calls indentLineOrRegion.
Otherwise (i.e. no multi-line selection, tabAlwaysIndent is false), the behavior depends on the location of the caret.
If the caret is at the very beginning of the text on the line, or in the whitespace to the left of the text, tab calls indentLine. If the caret is in the midst of the actual text on the line, tab inserts either a single tab character or the equivalent number of spaces, depending on the setting of the useTabs property.
Default key mapping: Tab (in programming modes)

Wraps all the lines in the current multi-line comment at the wrap column,
which by default is column 80. The wrap column is controlled by the property
wrapCol, which is a buffer-specific
setting that may be inspected and modified in the Properties dialog (see
properties). You can set global and mode-specific
defaults for wrapCol in your
preferences file.
Default key mapping: F12 in Java, Lisp, C, C++ and Perl modes
See also: wrapParagraph,
wrapRegion
Wraps all the lines in the current paragraph at the wrap column, which by default is column 80. The wrap column is controlled by the property wrapCol, which is a buffer-specific setting that may be inspected and modified in the Properties dialog (see properties). You can set global and mode-specific defaults for wrapCol in your preferences file.
A paragraph is basically defined as a block of contiguous lines with blank lines before and after it. To make the definition a bit more flexible, a line starting with <p>, <br> or <pre> is recognized as the first line of a paragraph, even if the line before it is not blank. Similarly, a line ending with <p>, </p>, <br> or </pre> is recognized as the last line of a paragraph, even if the line after it is not blank.
This function does not move the caret, so you can reformat the paragraph and immediately continue typing right where you left off.

to the specifed file, in human-readable form. The local key map supplements
(and possible overrides) global key assignments, based on the mode (Java, HTML,
etc.) of the buffer.
Default key mapping: None
Inserts '=' at the current location of the caret.
In XML mode, if the '=' immediately follows an attribute name, and if the
character following the '=' is either whitespace or '>', this command inserts
a pair of double quotation marks after the '=' and positions the caret between
the quotation marks.
The effect of this is to make it possible to enclose attribute values in quotation marks without having to type the quotation marks themselves.
Default key mapping: '=' in XML mode
See also: htmlElectricEquals
Inserts '/' at the current location of the caret.
In XML mode, if the '/' immediately follows '<', and if there is an unmatched start tag before the current location of the caret, the corresponding end tag is automatically inserted. The line is then automatically re-indented if autoIndent is true for the current buffer.
Default key mapping: '/' in XML mode
In XML mode, if XML parser support is available and the document tree is
displayed in the sidebar, forces the tree to expand all the way down to the
node corresponding to the location of the caret in the edit buffer.
Default key mapping: Ctrl = in XML mode
See also: XML Mode
Finds the match to the XML tag at the location of the caret. Nested tags are
handled correctly.
Default key mapping: Ctrl M in XML mode

If there is an unmatched start tag before the current location of the caret, automatically inserts the corresponding end tag.
Default key mapping: Ctrl E in XML mode
Inserts an XML start tag and the corresponding end tag, enclosing the current
selection. If no selection is marked, the start and end tags enclose the word
at the current location of the caret, if any.
If the property XmlMode.fixCase
is true, the tag name is converted to the preferred case (as specified by
XmlMode.upperCaseTagNames)
when it is inserted in the buffer.
Default key mapping: Ctrl Shift , (Ctrl Shift comma) in XML mode
In XML mode, parses the current buffer. If the operation succeeds, the document tree in the sidebar is updated.
If there are errors or warnings, the parser's error messages are displayed in a transient output buffer. You can use the commands nextError, previousError and thisError to jump to the location of each error in the source.
