Vim view all your maps

For each way you can map something in Vim, you can inspect those mappings. Check out this table of commands:

     COMMANDS                    MODES
:map   :noremap  :unmap     Normal, Visual, Select, Operator-pending
:nmap  :nnoremap :nunmap    Normal
:vmap  :vnoremap :vunmap    Visual and Select
:smap  :snoremap :sunmap    Select
:xmap  :xnoremap :xunmap    Visual
:omap  :onoremap :ounmap    Operator-pending
:map!  :noremap! :unmap!    Insert and Command-line
:imap  :inoremap :iunmap    Insert
:lmap  :lnoremap :lunmap    Insert, Command-line, Lang-Arg
:cmap  :cnoremap :cunmap    Command-line
:tmap  :tnoremap :tunmap    Terminal-Job

To take a very practical one, :nmap will show you all of your normal mode mappings. Find a new command to try; you are not using them all (neither am I).

See help map.txt in Vim for more information.
