If not...should be included as a option for the next big upgrade. Just a suggestion. Thanks.
Opus already does it.
If you assign a hotkey to a Favorite then it will be listed in the keyboard map (i.e. Settings -> Customize -> Keys).
To assign a hotkey to a Favorite, select Favorites -> Edit Favorites, then edit the favorite in question (double-clicking it is the easiest way to do that) and you'll see a hotkey field.
Alternatively, if you only want a hotkey and don't want the path to be listed in your favourites, you could create a standalone hotkey which uses the Go command.
