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.
