I can\'t seem to find a way to map
and
in Vim. Is it possible?
Don't be so pessimistic about making a shortcut. There are outside options. Try the following code in AutoHotKey. [All you need is download and install AHK and run the following code as a script.]
#IfWinActive ahk_class Vim
^+!left:: send :s/{^}/`%/g{Enter}{$}o{enter} ; This is for commenting in tex files. you may change `% to be other symbles.
^,:: send ^ww
+^,:: send ^wW
Hope this would help with your problem.
