Detect if a key is bound to something in vim

Question

I\'d like to know if there is a way to figure out if a key does something in vim. I know that I can use :map to see user-defined mappings, but is there somethin

Answer 1

To check the default mapping:

:help index

For other mapping that is done by either users or plugin:

:map
:map!

From http://vim.wikia.com/wiki/Mapping_keys_in_Vim_-Tutorial(Part_1):

The first command displays the maps that work in normal, visual and select and operator pending mode. The second command displays the maps that work in insert and command-line mode.

Typically the output of the above commands will span several pages. You can use the following set of commands to redirect the output to the vim_maps.txt file:

:redir! > vim_maps.txt
:map
:map!
:redir END
