When defining a buffer-local mapping for "," there may be a global mapping
|
|
that starts with ",". Then you need to type another character for Vim to know
|
|
whether to use the "," mapping or the longer one. To avoid this add the
|
|
<nowait> argument. Then the mapping will be used when it matches, Vim does
|
|
not wait for more characters to be typed.

If the first argument to one of these commands is "<script>" and it is used to

define a new mapping or abbreviation, 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.
