Question about full description popups

[E3D3]

Thank you for sharing this helpful package.

Because I avoid the mouse it took a while before I discovered that which-key displays the full command description on mouse hoover over a command. Below a screenshot with the which-key buffer on the left and an ibuffer buffer on the right:

I couldn't find anything about this in the docs so maybe this feature is provided by another of my installed packages. Is that right ?
If so then maybe it is nice to tell about it in the documentation, if known which program extends it 😕
If it is a builtin feature then this should also be added to the documentation IMHO.

ok, want to make a pr?

and yes, it's being added by which-key. The documentation for the function is embedded in the "face"

Sorry, I don't have, (nor want to investigate in) more github skills than simple typing and clicking buttons.
