From time to time I want to search on the list of my currents mappings. I search either for mapped keys (what /<Space>a does?) or for a command (What keys are mapped on /MyFunction()<CR>?)

I know that I can output these mappings with :map (or :nmap, :vmap, etc...) but this open a window where I can only scroll and not use search mode /.

So when I want to search in this list I have to use redir to put the result of the command in a new file, which I then open in vim and use search mode:

:redir > foo
:redir END
:e foo

I feel like this workflow is not natural:

  • It uses a lots of commands compared to what I want to do.
  • It creates a new file that I have to delete.

So my question is is there a more natural way to do a search in the currently mapped keys?

I know that I could create a function which would executes these commands and a custom command to easily call the function, but I was wondering if there wouldn't be a more straight forward way to do it.

A very easy way to search for a mapping uses a plugin. But the good news is, you probably have it already.

The command is:

:Unite mapping -start-insert

... then you basically directly type your search term and narrow down the list.

Without a plugin, you can still narrow your map results by providing the prefix of the map, and its type. For example:

:verbose xmap <leader>

... will show the defined mappings only for visual mode, and which start with the leader key. You are not limited to one character there (e.g. you can use xmap <leader>a and so on).

  • I heard of this plugin before but never tried it I'll give it a try thanks! Also the second suggestion is nice but doesn't allow to do the second type of search i.e. which keys are mapped to execute this function.

  • Indeed - you can do that with the 1st suggestion. And 'Unite' (and its extensions) = the Swiss knife of Vim plugins :)

:map, :imap and friends take an argument so, instead of issuing a generic command and then filtering it you could simply issue a specific command from the get go:

:imap <CR>

    That's a great way to do it thanks but as for VanLaser answer I stil have a question: this doesn't allow me to make a search on MyFunction to know which keys are mapped to call it.
