I tried to define a keyboard shortcut for "Blackout" (the letter "b").
I cannot find a way to remove it, in order to have no more shortcut for that.
Typing blank leaves the same key when the preferences window is opened again. Delete does nothing either.
Furthermore, with a keyboard key, blackout remains while the key is pressed. When the keyboard key is released, there is no more blackout.
Intentional ?
