[TxMt] Unused key-bindings

[Xavier Cambar]

Hi there,
I was just wondering if there was a way to know if a key combination  
was assigned to a particular action.

Why: I would like to avoid as much as possible the use of the pop-up  
showing the corresponding actions, and so, assign a unique action per  
shortcut per scope.
Even if there is the "Show Keyboard Shortcuts" command, it could be  
more useful to type in the shortcut you want to test, and you get as  
the result a list of actions assigned to that shortcut.

Thanks in advance,
Xavier Cambar
