This option
	is used for the commands "[i", "]I", "[d", etc.
	Normally the 'isfname' option is used to recognize the file name that
	comes after the matched pattern.  But if "\zs" appears in the pattern
	then the text matched from "\zs" to the end, or until "\ze" if it
	appears, is used as the file name.  Use this to include characters
	that are not in 'isfname', such as a space.  You can then use
	'includeexpr' to process the matched text.
	See |option-backslash| about including spaces and backslashes.

						*'includeexpr'* *'inex'*
'includeexpr' 'inex'	string	(default "")
			local to buffer
	Expression to be used to transform the string found with the 'include'
	option to a file name.  Mostly useful to change "." to "/" for Java: >vim
		setlocal includeexpr=substitute(v:fname,'\\.','/','g')
<	The "v:fname" variable will be set to the file name that was detected.
	Note the double backslash: the `:set` command first halves them, then
	one remains in the value, where "\." matches a dot literally.  For
	simple character replacements `tr()` avoids the need for escaping: >vim
		setlocal includeexpr=tr(v:fname,'.','/')
<
	Also used for the |gf| command if an unmodified file name can't be
	found.  Allows doing "gf" on the name after an 'include' statement.
	Note: Not used for |<cfile>|.

	If the expression starts with s: or |<SID>|, then it is replaced with
	the script ID (|local-function|). Example: >vim
		setlocal includeexpr=s:MyIncludeExpr()
		setlocal includeexpr=<SID>SomeIncludeExpr()
<	Otherwise, the expression is evaluated in the context of the script
	where the option was set, thus script-local items are available.

	It is more efficient if the value is just a function call without
	arguments, see |expr-option-function|.

	The expression will be evaluated in the |sandbox| when set from a
	modeline, see |sandbox-option|.
	This option cannot be set in a modeline when 'modelineexpr' is off.

	It is not allowed to change text or jump to another window while
	evaluating 'includeexpr' |textlock|.

				*'incsearch'* *'is'* *'noincsearch'* *'nois'*
'incsearch' 'is'	boolean	(default on)
			global
	While typing a search command, show where the pattern, as it was typed
	so far, matches.  The matched string is highlighted.  If the pattern
	is invalid or not found, nothing is shown.  The screen will be updated
	often, this is only useful on fast terminals.
	Note that the match will be shown, but the cursor will return to its
	original position when no match is found and when pressing <Esc>.  You
	still need to finish the search command with <Enter> to move the
	cursor to the match.
	You can use the CTRL-G and CTRL-T keys to move to the next and
	previous match. |c_CTRL-G| |c_CTRL-T|
	Vim only searches for about half a second.  With a complicated
	pattern and/or a lot of text the match may not be found.  This is to
	avoid that Vim hangs while you are typing the pattern.
	The |hl-IncSearch| highlight group determines the highlighting.
	When 'hlsearch' is on, all matched strings are highlighted too while
	typing a search command. See also: 'hlsearch'.
	If you don't want to turn 'hlsearch' on, but want to highlight all
	matches while searching, you can turn on and off 'hlsearch' with
	autocmd.  Example: >vim
		augroup vimrc-incsearch-highlight
		  autocmd!
		  autocmd CmdlineEnter /,\? :set hlsearch
		  autocmd CmdlineLeave /,\? :set nohlsearch
		augroup END
<
	CTRL-L can be used to add one character from after the current match
	to the command line.  If 'ignorecase' and 'smartcase' are set and the
	command line has no uppercase characters, the added character is
	converted to lowercase.
	CTRL-R CTRL-W can be used to add the word at the end of the current
	match, excluding the characters that were already typed.

						*'indentexpr'* *'inde'*
'indentexpr' 'inde'	string	(default "")
			local to buffer
	Expression which is evaluated to obtain the proper indent for a line.
	It is used when a new line is created, for the |=| operator and
	in Insert
