NAME

keys - a

Key Syntax
----------
Usual keys are written using their ascii character, including capital
keys. Non printable keys use an alternate name, written between *<*
and *>*, such as *<esc>* or *<del>*. Modified keys are written between
*<* and *>* as well, with the modifier specified as either *c* for
Control, or *a* for Alt, followed by a *-* and the key (either its
name or ascii character), for example *<c-x>*, *<a-space>*.

In order to bind some keys to arbitrary ones, refer to the 'mapping'
documentation page.

Insert mode
-----------
*<esc>*::
	leave insert mode

*<backspace>*::
	delete characters before cursors

*<del>*::
	delete characters under cursors

*<left>*, *<right>*, *<up>*, *<down>*::
	move the cursors in given direction

*<home>*::
	move cursors to line begin

*<end>*::
	move cursors to end of line

*<c-n>*::
	select next completion candidate

*<c-p>*::
	select previous completion candidate

*<c-x>*::
	explicit insert completion query, followed by:

	*f*:::
		explicit file completion

	*w*:::
		explicit word completion

	*l*:::
		explicit line completion

*<c-o>*::
	disable automatic completion for this insert session

*<c-r>*::
	insert contents of the register given by next key

*<c-v>*::
	insert next keystroke directly into the buffer, without interpreting it

*<c-u>*::
	commit changes up to now as a single undo group

*<a-;>*::
	escape to normal mode for a single command

Using Counts
------------

In normal mode, commands can be prefixed with a numeric count, which can control
the command behaviour.

For example, *3W* selects 3 consecutive words and *3w* select the third word on
the right of selection end.

Disabling Hooks
---------------

Any normal mode command can be prefixed with *\* which will disable hook execution
for the duration for the command (including the duration of modes the command could
move to, so *\i* will disable hooks for the whole insert session).

As autoindentation is implemented in terms of hooks, this can be used to disable
it when pasting text.
