The following vi keys are supported for navigating and editing, after setting vi Mode in the options. Most keys follow the open group specifations for vi and ex

ex commands command keys action abbreviate :ab [lhs rhs] Abbreviate lhs for rhs adjust window :[1addr]z[type][count][flags] Print the specified line with context. If count is not specified, it default is 2. Type can be: - : The specified line shall be decremented by the following value: (((number of "-" characters) x count) -1) + : The specified line shall be incremented by the following value: (((number of "+" characters) -1) x count) + ^ : The specified line shall be decremented by the following value: (((number of "^" characters) +1) x count) -1 = : Embed context into lines of 40 - characters, with (count -1) / 2 around match . : show context with (count -1) / 2 around match append :[1addr]a Enter ex text input mode; the input text is placed after the specified line. arguments :ar Shows command line arguments, if provided change :[2addr]c The input text replaces the specified lines close :close Closes current document copy :[2addr]t 1addr Copy the specified lines after the specified destination line de :de debug Performs debug action, as available in debug menu from menus.xml delete :[2addr]d[buffer] Delete the specified lines into a buffer (defaulting to the unnamed buffer) edit :e [file] If no file is specified shows select file dialog, otherwise edits file escape :!command :[2addr]!command If no lines are specified executes command and shows output. If lines are specified, they are passed to the program as standard input, and the standard output and standard error of the program replaces those lines in the edit buffer. global :[2addr]g/pattern/[commands] :[2addr]v/pattern/[commands] If pattern and commands are empty: remove all markers otherwise if commands are empty: mark lines containing pattern otherwise executes all commands for each line matching pattern, commands separated by |, or (for v) executes all commands for each line not matching pattern goto :[1addr] Goto specified address grep :grep [match][extension][folder][options] If nothing specified shows find in files dialog, otherwise greps for match in folder matching file extension using options: /r: recursive help :help Shows help indent :[2addr][>|<] Increase, decrease indent for range insert :[1addr]i Enter ex text input mode; the input text is placed before the specified line. join :[2addr]j Joins lines mark :[1addr]kcharacter Marks address with character move :[2addr]m 1addr Move the specified lines after the specified destination line x new :new New document (dialog) print :[2addr]p[flags] :print [file] Write the addressed lines If the # flag is specified, each line is preceded by line number. The second synopsis shows print dialog if file is not spcified, otherwise prints file. put :[1addr]pu[buffer] Append text from the specified buffer (by default, the unnamed buffer) to the specified line quit :q [!] Quit unless modified, quit forced read :[1addr]r [!][file] If ! not specified insert contents of file below cursor, otherwise inserts output or running file command below cursor register :reg Shows registers (buffers) and variables from calculation mode sed :sed [match replace][extension][folder][options] If nothing specified shows replace in files dialog, otherwise replaces match by replace in folder matching file extension using options: /r: recursive set :set [options] If options not specified shows options dialog, otherwise sets specified options sort :[2addr]S[options] Sorts range by lines using options: r: reverse u: unique x,y: use columns source :so file Executes all commands from file substitute :[2addr]s/pattern/repl/[options] :[2addr]&[options] :[2addr]~[options] Replace the first instance of the pattern pattern by the string repl on each specified line. If both pattern and repl are not specified or are empty (for example, "//" ), the last s command is repeated. If only pattern is not specified or is empty, the last regular expression used in the editor is used as the pattern. Supported options: i: ignore case c: ask for confirmation g: global, otherwise only first match on line When substituting you can use & or \0 to represent the target, and \U to convert to uppercase and \L to convert to lowercase. You can use a $ to match a line end, e.g. %s/$/EOL appends the string EOL at the end of each line. Merging is not yet possible using a \n target, you can create a macro for that. You can use ~ to match against a previous replacement string. syntax :syntax options Use syntax highlighting, options are on or off tab :n :prev Next or previous tag :ta tag Jumps to tag unabbreviate :una lhs Unabbreviate lhs version :ve Shows version write :[2addr]w [>>][file] If no lines are specified, the entire file is used. If the >> argument is specified, and the file already exists, the lines are appended to the file instead of replacing its contents. write and exit :x Save and quit write line :[1addr]= Shows line number yank :[2addr]y[buffer] Copy the specified lines to the specified buffer (by default, the unnamed buffer)

Each motion command can be prefixed with a multidigit number, that takes care of repeating that command the number specified, and by a c, d, y character that changes, deletes or yanks the specified motion.

Where:

[1addr]

A single line address

chars	range
.	current line
$	last line
'character	line that contains mark character
line no	line number

[2addr]

Two addresses specifying an inclusive range of lines.

chars	range
%	entire document
*	visible area
'<,'>	visual (selected) area
[1addr],[1addr]	inclusive range of lines

[buffer]

name	purpose	explanation
.	insert register	last inserted text
0	yank register (or unnamed buffer)	last yank value
1 - 9	delete registers	queue of 9 last deleted values
a - z	standard registers	normal register
*	clipboard register	contents of clipboard
%	filename register	current filename
_	black hole register	anything written to it is not kept

[Calculation mode]

operator	description
+	add
-	subtract
*	multiply
/	divide
<<	shift left
>>	shift right
.	current line
$	line count
%	modulo
|	bitwise or
&	bitwise and
^	bitwise xor
XXX=2	assigns to variable XXX

You can also insert contents of markers, or of registers, or use parenthesis to group expressions.

[Edit Options]

all set commands can be entered as modeline as well, at begin or end of file

command	purpose
:set ac	toggles auto complete
:set ai	toggles auto indentation
:set el	toggles edge line
:set ic	toggles ignore case
:set mw	toggles match words
:set nu	toggles line numbers
:set re	toggles regular expression
:set sm	toggles showing vi mode
:set ut	toggles use tabs
:set wl	toggles wrap line
:set ws	toggles whitespace
:set ec=no	sets edge column
:set sw=no	sets indentation
:set sy=lexer	sets lexer
:set ts=no	sets tabstop at every no

Replace uses regular expressions from std::regex or from scintilla (if compiler flag NO_CXX11_REGEX is defined, which is the default):

char	purpose
.	Matches any character
\(	This marks the start of a region for tagging a match.
\)	This marks the end of a tagged region.
\n	Where n is 1 through 9 refers to the first through ninth tagged region when replacing. For example, if the search string was Fred\([1-9]\)XXX and the replace string was Sam\1YYY, when applied to Fred2XXX this would generate Sam2YYY. \0 refers to all of the matching text.
\<	This matches the start of a word using Scintilla's definitions of words.
\>	This matches the end of a word using Scintilla's definition of words.
\x	This allows you to use a character x that would otherwise have a special meaning. For example, \[ would be interpreted as [ and not as the start of a character set.
[...]	This indicates a set of characters, for example, [abc] means any of the characters a, b or c. You can also use ranges, for example [a-z] for any lower case character.
[^...]	The complement of the characters in the set. For example, [^A-Za-z] means any character except an alphabetic character.
^	This matches the start of a line (unless used inside a set, see above).
$	This matches the end of a line.
*	This matches 0 or more times. For example, Sa*m matches Sm, Sam, Saam, Saaam and so on.
+	This matches 1 or more times. For example, Sa+m matches Sam, Saam, Saaam and so on.

Regular expressions will only match ranges within a single line, never matching over multiple lines.
