Annotate Key Remapping

[GreasySlug]

Describe your feature request

Suppose you have created a new keymap in your user settings.
e.g.

[keys.insert]
j = { j = "normal_mode", s = ":write" , C-s = [":write", ":format"] }

then, the infobox displays like this

+--------------------------+
| j Enter normal mode |
| C-s [Multiple commands] |
| s :write[] |
+--------------------------+

I want the it to be displayed like this

+-------------------------+
| j Enter normal mode |
| C-s write and format |
| s write |
+-------------------------+

If you don't annotate anything, it will display as before.
If annotated, override the infobox.

This seems to actually be a duplicate of #1487 and #1752
