[REQUEST] add more details to `:debug mappings` and/or provide an additional command that shows all bindings about kakoune

[Screwtapello]

It would definitely be helpful to have the right-hand-side of the mapping included in the debug output, even if only just for mappings that do not include a docstring (which is most of them).

It only seems to show mappings that have been modified from the defaults

Technically, that's what a mapping is: a modification from the defaults. h isn't mapped to the "move left" command, it is the "move left" command.

On one hand, it might be nice to have better visibility on the current state of the system; on the other hand, Kakoune tries pretty hard to discourage people from building abstractions - all the mappings in your configuration should be ones you put there yourself, not introduced by a plugin.

Maybe the best output would be to dump the mappings as valid kakscript? Just a thought.

for learning default mappings I used this command though it leaves some things to be desired (only works for normal mode).
I imagine it would be nice if there was a mechanical way to find out the meaning of a single key (whether mapped or not), something like Emacs' C-h k but it's not clear how it should work. I don't think :debug mappings is necessarily something for everyday use.
I agree the rhs should probably be included, should be easy to do

Indeed, this is what I was trying to express. It's one of the more mind-bending strokes of genius of this editor.

True. And :debug mappings is already useful enough to show what's been modified. There should be a way to do that, come to think of it.

So maybe showing all the bindings might be best accomplished as an additional debug command called :debug all-keys or similar.

The display of the right hand side of the mapping is another little enhancement that would apply in either case.

If that's easy to do, that would probably be the highest impact change mentioned, even if the other things can't be done right now (output unchanged defaults, add docstrings to everything).

That would be great! It also sounds like something that could be made difficult due to implementation details I don't really understand.

Since that's a really specific change, I will open a separate issue for just adding rhs to :debug mappings. This issue can remain open and we can keep brainstorming on improvements to interactive feedback on current key mappings. #5152
