Vim tool to show keyboard shortcuts for typed commands?

Question

I am learning Vim by typing some commands in full rather than using keyboard shortcuts. Is there a tool or plugin that can show me the equivalent shortcuts if they exist, whether they are built in defaults, set by plugins or are user configured?

Answer 1

Shows built-in abbreviations for command quit

:help :quit

Outputs:

:q[uit]   Quit the current window.  Quit Vim if this is the last
          window.  This fails when changes have been made and
          ...

The square brackets indicate the unnecessary characters for the command. Any of the following are equivilant to quit:

:q
:qu
:qui
:quit

You can even abbreviate the command you are getting help for. For example :h :q gets help for quit

Shows mapped shortcuts

:map

Shows mapped shortcuts for a specific mode

:imap
:nmap
:cmap
etc...

Shows abbreviations

:abbr

Finds all mappings associated with a command

For example, to find all mappings that use :call

:new
:redir @a
:map
:redir END
:put a
/:call

Explanation: create a new buffer, redirect output to register a, list all mappings, finish redirect, paste register a, search for your command

Shows purely built-in mappings

vim -u NONE
:map

Shows user customizations

:e $MYVIMRC

Show plug-ins

:scriptnames

anything not a built-in or user customization could be from one of the plugins. You could grep the files in scriptnames for your command

I'm by no means a vi expert. I'm certain there are many other ways to get the information you want. This is just how I would go about it.
