= Mapping
== Description
Creating and removing shortcuts boils down to the following commands,
respectively:
---------------------------------------
map [flags] <scope> <mode> <key> <keys>
unmap <scope> <mode> <key> [<expected>]
---------------------------------------
The *map* command makes *key* behave as if the *keys* sequence was typed.
*mode* dictates in what context the mapping will be available:
*insert*::
insert mode
*normal*::
normal mode
*prompt*::
prompts, such as when entering a command through *:*, or a regex through */*
*menu*::
mode entered when a menu is displayed with the 'menu' command
*user*::
mode entered when the user prefix is hit (default: ',')
*goto*::
mode entered when the goto key is hit (default: 'g')
*view*::
mode entered when the view key is hit (default: 'v')
*object*::
mode entered when an object selection is triggered (e.g. '<a-i>')
The context of execution of the above modes is always the current one at the
time of execution of the mapping, except for *user* mode (always executed
in a 'normal' context).
An optional *-docstring* switch followed by a string can be used
to describe what the mapping does. This docstring will be used
in autoinfo boxes.
The *unmap* command removes a mapping of *key* in the given *scope* and
*mode*. If *expected* is specified, the mapping is removed only if it is
set to the same sequence of keys passed using the *expected* argument.
For more information about the values of the *scope* parameter, refer to
<<scopes#,`:doc scopes`>>.
== Mappable keys
For *key* and *keys* in the *map* command, the following key names can
be used:
*x*, *<x>*::
Most keys, especially alphabetic keys, represent themselves.
Keys can also be wrapped in angle-brackets for consistency
with the non-alphabetic keys below.
*X*, *<X>*::
Holding down Shift while pressing the *x* key.
*<c-x>*::
Holding down Control while pressing the *x* key.
*<a-x>*::
Holding down Alt while pressing the *x* key.
*<c-a-x>*::
Holding down Control and Alt while pressing the *x* key.
*<lt>*, *<gt>*::
The *<* and *>* characters.
*<plus>*, *<minus>*::
The *+* and *-* characters..
*<ret>*::
The Return or Enter key.
*<space>*::
The space bar.
*<tab>*::
The Tab key.
*<backtab>*::
The reverse-tab key. This is Shift-Tab on most keyboards.
*<backspace>*::
The Backspace (delete to the left) key.
*<del>*::
The Delete (to the right) key.
*<esc>*::
The Escape key.
*<up>*, *<down>*, *<left>*, *<right>*::
*<pageup>*, *<pagedown>*, *<home>*, *<end>*::
The usual cursor-movement keys.
*<f1>*, *<f2>*, ...*<f12>*::
Function keys.
