viewable list of unassigned keyboard shortcut keys?

is there a way to view a list all keyboard shortcut combos YET UNassigned?
in TV Paint there’s a column much like that in TBHarmony with nested subcategories,
but there’s also a parallel list of ALL possible key combinations with the currently assigned AND yet-unassigned blank ones all visible together, so at a glance you can easily see which key combos are available.
i’ll post a screen capture.

maybe there’s a TBH way to see a list like this too?


I don’t think that there is a way to see the anissigned keyboard shortcut combinations at present. But I like the idea!!
