The number of help item matches is limited (currently to 300) to avoid a long
delay when there are very many matches.

These are the commands that can be used:

							*c_CTRL-D*
CTRL-D		List names that match the pattern in front of the cursor.
		When showing file names, directories are highlighted (see
		|highlight-groups|).  Names where 'suffixes' matches are moved
		to the end.
		The 'wildoptions' option can be set to "tagfile" to list the
		file of matching tags.
					*c_CTRL-I* *c_wildchar* *c_<Tab>*
'wildchar' option
		A match is done on the pattern in front of the cursor.  The
		match (if there are several, the first match) is inserted
		in place of the pattern.  (Note: does not work inside a
		macro, because <Tab> or <Esc> are mostly used as 'wildchar',
		and these have a special meaning in some macros.) When typed
		again and there were multiple matches, the next
		match is inserted.  After the last match, the first is used
		again (wrap around).
		The behavior can be changed with the 'wildmode' option.
							*c_<S-Tab>*
<S-Tab>		Like 'wildchar' or <Tab>, but begin with the last match and
		then go to the previous match.
							*c_CTRL-N*
CTRL-N		After using 'wildchar' which got multiple matches, go to next
		match.  Otherwise recall more recent command-line from history.
							*c_CTRL-P*
CTRL-P		After using 'wildchar' which got multiple matches, go to
		previous match.  Otherwise recall older command-line from
		history.
							*c_CTRL-A*
CTRL-A		All names that match the pattern in front of the cursor are
		inserted.
							*c_CTRL-L*
CTRL-L		A match is done on the pattern in front of the cursor.  If
		there is one match, it is inserted in place of the pattern.
		If there are multiple matches the longest common part is
		inserted in place of the pattern.  If the result is shorter
		than the pattern, no completion is done.
							*/_CTRL-L*
		When 'incsearch' is set, entering a search pattern for "/" or
		"?" and the current match is displayed then CTRL-L will add
		one character from the end of the current match.  If
		'ignorecase' and 'smartcase' are set and the command line has
		no uppercase characters, the added character is converted to
		lowercase.
	                                            *c_CTRL-G* */_CTRL-G*
CTRL-G		When 'incsearch' is set, entering a search pattern for "/" or
		"?" and the current match is displayed then CTRL-G will move
		to the next match (does not take |search-offset| into account)
		Use CTRL-T to move to the previous match.  Hint: on a regular
		keyboard T is above G.
	                                            *c_CTRL-T* */_CTRL-T*
CTRL-T		When 'incsearch' is set, entering a search pattern for "/" or
		"?" and the current match is displayed then CTRL-T will move
		to the previous match (does not take |search-offset| into
		account).
		Use CTRL-G to move to the next match.  Hint: on a regular
		keyboard T is above G.

The 'wildchar' option defaults to <Tab> (CTRL-E when in Vi compatible mode; in
a previous version <Esc> was used).  In the pattern standard |wildcards| are
accepted when matching file names.

When repeating 'wildchar' or CTRL-N you cycle through the matches, eventually
ending up back to what was typed.  If the first match is not what you wanted,
you can use <S-Tab> or CTRL-P to go straight back to what you typed.

The 'wildmenu' option can be set to show the matches just above the command
line.

The 'wildoptions' option provides additional configuration to use a popup menu
for 'wildmenu', and to use fuzzy matching.

The 'wildignorecase' option can be set to ignore case in filenames.  For
completing other texts (e.g. command names), the 'ignorecase' option is used
instead (fuzzy matching always ignores
