Question

I write a lot of code and tired of pressing shift each time I need a special character. And since I use special chars much often, then numbers, I want to reverse shift behavior on them.

So, if I type <4> I’ll get ‘$’ and if I type <shift>+<4> I’ll get ‘4’ and so on for each number. This mapping should work only in insert mode.

I’ve tried:

:set langmap 123...;!@#...,!@#...;123 "works only in normal-mode

:imap 4 $
:imap $ 4 "recursive mapping error

Answer 1

Use :ino, which does the same thing as :imap except that it doesn’t look for maps in the replaced text. (it’s short for ‘inoremap’) That will fix the recursion issue.

Or type :h map for vim online help (same thing, just inside vim).
