Is there some way to list unused keybinds? I guess if the answer is no, it would be a good feature-request (especially for these undecided types like myself).

Edit: To make it more precise, I know you can list bindings with:

:map
:nmap
:imap

FFI see:

:help map-modes

and manually check whether given binding is used by typing e.g.:

:help Ctrl-w
:help ^w

FFI see:

:help map

    This doesn't answer your question but is related (for future searches). You may be interested in `:help map-which-keys`. – Randy Morris May 10 '11 at 10:57

  • @RandyMorris - great help topic suggestion! I was actually missing something like this: http://hea-www.harvard.edu/~fine/Tech/vi.html - but for Vim. Then I found out about `:help index` - which is also great. I need some mappings for missing functionality (e.g. in Cmder `^W` will kill your console, and `^V` pastes clipboard (and Alt-^-V does nothing). – Tomasz Gandor Sep 18 '17 at 11:18

    What does "FFI" mean? "For further information"? – Kenny Evitt Jul 08 '19 at 22:14

To my knowledge there is no way to list the unused key-bindings (this would be impossible because there is an infinite number of them).

But if you want to go the other way around you can type:

:map

:imap

to list the user defined key-bindings.

Also if you type 

:help index

you can check if some key-binding is already assigned to a function in vim.

    It's infinite but you can definitely introduce some order into that set or add maximal length parameter. – derenio May 10 '11 at 09:18
