Help about a remembered key stroke

[halloleo]

VisiData comes with a good built-in documentation listing long commands and key shortcuts. (z ^h)

Sometimes however it could be nice to type a key stroke and get a help on what only this key stroke would do.

Emacs offers this with ^h k followed by the key stroke. So, for example ^h k ^x ^s brings up the help about the save-buffer command (initiated via keyboard by ^x ^s).

This is pretty invaluable when you quickly want to check whether your memory about a command is correct.

Just an idea...

Interesting idea, @halloleo ! I don't think we can use Ctrl+H for this; what keystroke would you suggest?

[Mickychen00]

Like the WhichKey Plugin in Vim/Neovim?

[halloleo]

@saulpw Of course, Ctrl-H is taken. Not sure what would fit with the carefully crafted visidata key scheme... Maybe just a long-command users can bind?

@Mickychen00 I don't know vim well, but often I have a keye combo in mind, but want to doublecheck whether it really does what I want...

It could be a long command, like :help in vim.

For example, in Vim I can type either :help ^f or :help ctrl-f to learn more about the ctrl-f command.
However, this requires you to type the symbolic form of the command, rather than the command itself.
Perhaps another long command help-interactive could pop up a dialog and wait for a key press, to provide help directly for shortcuts without needing to type them in symbolically?
