Problem: Cannot easily restore a mapping.
Solution: Add mapset().
rhs of mapping {name} in mode {mode}
mapcheck({name} [, {mode} [, {abbr}]])
String check for mappings matching {name}
+mapset({name}, {mode}, {abbr}, {dict}
+ none restore mapping from |maparg()| result
match({expr}, {pat} [, {start} [, {count}]])
Number position where {pat} matches in {expr}
matchadd({group}, {pattern} [, {priority} [, {id} [, {dict}]]])
Can also be used as a |method|: >
mylist->map(expr2)
+
maparg({name} [, {mode} [, {abbr} [, {dict}]]]) *maparg()*
When {dict} is omitted or zero: Return the rhs of mapping
{name} in mode {mode}. The returned String has special
"lnum" The line number in "sid", zero if unknown.
"nowait" Do not wait for other, longer mappings.
(|:map-<nowait>|).
+ "simplified"
+
+ The dictionary can be used to restore a mapping with
+ |mapset()|.
The mappings local to the current buffer are checked first,
then the global mappings.
Can also be used as a |method|: >
GetKey()->mapcheck('n')
+mapset({mode}, {abbr}, {dict}) *mapset()*
+ Restore a mapping from a dictionary returned by |maparg()|.
+ {name}, {mode} and {abbr} should be the same as for the call
+ to |maparg()|.
+ {mode} is used to define the mode in which the mapping is set,
+ not the "mode" entry in {dict}.
+ Example for saving and restoring a mapping: >
+ let save_map = maparg('K', 'n', 0, 1)
+ nnoremap K somethingelse
+ ...
+ call mapset('n', 0, save_map)
+<
match({expr}, {pat} [, {start} [, {count}]]) *match()*
When {expr} is a |List| then this returns the index of the
first item where {pat} matches. Each item is used as a
