So is it for example, the E for edge tools the type of menu you mean?

If so then I'd prefer not to have a menu hotkey as such.. Just allow
none unique key mappings and automatically generate a menu from all
items assigned to the key.

Then it'd just need remove(key, option) and add(key, option).. remove to
remove a default, and add to add one.

In your example there would be remove( G_KEY, translate) and add( M_KEY,
translate)

The update would make the remove obsolete as no default key, function
pairing would match (G_KEY, translate). This could be removed when
settings are next saved.

If I'd also got something else on CTRL-G, then I'd now start getting a
menu with "Translate" and my other option. I could manually resolve this
by adding a remove( CTRL_G_KEY, translate) entry or even remove( M_KEY,
translate) if I preferred the new default.

So if I use a hotkey with one assignment, just do it, otherwise generate
the options menu. Could even have a index / priority per assignment so
the popup menus be ordered for number hotkeys.
