I suppose that if you want to know "what was that mapping I put in for
that command" and don't even know where you defined it, it can be hard
to find.
You can use :filter:
:filter NextCommand map
But you have to redirect the output and process it, which can be tricky
for special keys.
I can't think of another function to use for this, thus adding mapfind()
seems useful. Would we also make it possible to find using the LHS?
At least the function name should somehow indicate matching the RHS, or
be able to do both.
