Is there any way to view the currently mapped keys in Vim?

:redir! > vim_keys.txt
:silent verbose map
:redir END

This outputs the shortcuts, with where they were defined, to a text file.

You can do that with the :map command. There are also other variants.

• :nmap for normal mode mappings
• :vmap for visual mode mappings
• :imap for insert mode mappings

The above list is not complete. Typing :help map in Vim will give you more info.
