:map
will type out all your normal/visual/operator-pending mappings (if any);
similarly with :map! for Insert/Command-line. In a script, you may want
to use
0verbose map
to make sure that Vim does _not_ display where the mapping was defined.
You can capture that output with the :redir command (even IIRC when
using the :silent prefix to avoid scrolling them all on the display).
Beware that there are sometimes additional letters saying if the map is
limited to some modes, has the <buffer> and/or <expr> modifiers, etc.
Some of these appear right before the {rhs} with no intervening space,
so you may have to do some fiddling around with the :redir output to
separate the {rhs}.
See
:help :map_l
" also the paragraph above it
:help map-listing
:help :verbose
:help :redir
Best regards,
Tony.
