:map x sequence
|
|
Define character x as a sequence of editing commands.
|
|
:unmap x
|
|
Disable the sequence defined for x.
|
|
:map
|
|
List the characters that are currently mapped.
|
|
|
|
|
|
:nmap - normal mode map
|
|
:vmap - visual mode map
|
|
:imap - insert mode map
|
|
:cmap - language mode map (ins, command-line, enter search pattern, cmd-arg)
|
|
:lmap - cmdommand-line mode map
|
|
:omap - operator-pending mode map
|
|
:smap - select mode map

|
Attributes:
|
|
|
|
<silent>
|
|
To define a mapping which will not be echoed on the command line
|
|
<buffer>
|
|
The mapping will be effective in the current buffer only
|
|
<expr>
|
|
Define a new mapping or abbreviation, the argument is an expression.
|
|
The expression is evaluated to obtain the {rhs} that is used.
|
|
<unique>
|
|
The command will fail if the mapping or abbreviation already exists
|
|
<script>
|
|
The mapping will only remap characters in the {rhs} using mappings that were defined local to a script,
|
|
starting with "<SID>".
|
|
This can be used to avoid that mappings from outside a script interfere
|
|
(e.g., when CTRL-V is remapped in mswin.vim), but do use other mappings defined in the script)
|
|
<special>
|
|
Define a mapping with <> notation for special keys, even though the "<" flag may appear in 'cpoptions'.
|
|
This is useful if the side effect of setting 'cpoptions' is not desired.
|
|
|
|
Chars, available in cmd-mode (for mapping):
|
|
Letters: g, K, q, V, v
|
|
Conrol : ^A, ^K, ^O, ^W, ^X
|
|
Symbols: _, *, \, =
|
|
F-keys: #1 ..
|
|
Specials: <Home>, ..
|
|
|
|
Protecting keys from interpretation: ^V (CTRL-V).
|
|
|
|
NOTE1: You can't insert vert-bar (|) in ex-commands!
|
|
NOTE2: Vim remap option controls nested mapped commands!
|
|
|
|
|
|

|

:vmap - reassign visual mode keys

|
:vmap > >gv - then you type '>' execute '>gv' (shift the text right, re-select it, and go back to the visual mode)
