Question

Is there a way to find out that my new mapping won’t collide with some keyboard shortcut already set in vim? For example I will want to map gg to something because I don’t know that vim uses it to go to the beginning of the file. How to get know that this mapping is already used for another purpose?

thank you

Answer 1

I tend to run :help gg or :help _ or :help ctrl-y to see if the mapping I’m thinking of over-writing is useful to me or not.

The ^D completion command can be helpful, try this:

:help ctrl^D

That’s typing ctrl with four letters, then hitting Control+D to get completion list. It shows help topics matching ctrl.

Typically, \ or , or _ characters are used as ‘leader’ characters, and you place all your mappings behind it. Not as convenient, but when everything is already taken…
