:nunmap can also be used outside of a monastery.
						*mapmode-x* *mapmode-s*
Some commands work both in Visual and Select mode, some in only one.  Note
that quite often "Visual" is mentioned where both Visual and Select mode
apply. |Select-mode-mapping|
NOTE: Mapping a printable character in Select mode may confuse the user.  It's
better to explicitly use :xmap and :smap for printable characters.  Or use
:sunmap after defining the mapping.

* If 'iminsert' is 1, see |language-mapping| below.

The original Vi did not have separate mappings for
Normal/Visual/Operator-pending mode and for Insert/Command-line mode.
Therefore the ":map" and ":map!" commands enter and display mappings for
several modes.  In Vim you can use the ":nmap", ":vmap", ":omap", ":cmap" and
":imap" commands to enter mappings for each mode separately.

							*omap-info*
Operator-pending mappings can be used to define a movement command that can be
used with any operator.  Simple example: >
	:omap { w
makes "y{" work like "yw" and "d{" like "dw".

To ignore the starting cursor position and select different text, you can have
the omap start Visual mode to select the text to be operated upon.  Example
that operates on a function name in the current line: >
	onoremap <silent> F :<C-U>normal! 0f(hviw<CR>
The CTRL-U (<C-U>) is used to remove the range that Vim may insert.  The
Normal mode commands find the first '(' character and select the first word
before it.  That usually is the function name.

To enter a mapping for Normal and Visual mode, but not Operator-pending mode,
first define it for all three modes, then unmap it for
Operator-pending mode: >
	:map    xx something-difficult
	:ounmap xx

Likewise for a mapping for Visual and Operator-pending mode or Normal and
Operator-pending mode.

						*language-mapping*
":lmap" defines a mapping that applies to:
- Insert mode
- Command-line mode
- when entering a search pattern
- the argument of the commands that accept a text character, such as "r" and
  "f"
- for the input() line
Generally: Whenever a character is to be typed that is part of the text in the
buffer, not a Vim command character.  "Lang-Arg" isn't really another mode,
it's just used here for this situation.
   The simplest way to load a set of related language mappings is by using the
'keymap' option.  See |45.5|.
   In Insert mode and in Command-line mode the mappings can be disabled with
the CTRL-^ command |i_CTRL-^| |c_CTRL-^|. These commands change the value of
the 'iminsert' option.  When starting to enter a normal command line (not a
search pattern) the mappings are disabled until a CTRL-^ is typed.  The state
last used is remembered for Insert mode and Search patterns separately.  The
state for Insert mode is also used when typing a character as an argument to
command like "f" or "t".
   Language mappings will never be applied to already mapped characters.  They
are only used for typed characters.  This assumes that the language mapping
was already done when typing the mapping. Correspondingly, language mappings
are applied when recording macros, rather than when applying them.


1.4 LISTING MAPPINGS					*map-listing*

When listing mappings the characters in the first two columns are:

      CHAR	MODE	~
     <Space>	Normal, Visual, Select and Operator-pending
