Chris@354:     // This workaround restores the single-key shortcut behaviour by
Chris@384:     // searching in menus for single-key shortcuts that are associated
Chris@384:     // only with the menu and not with a toolbar button, and

Chris@354:     //
Chris@384:     // (Previously this acted on all single-key shortcuts in menus,

Chris@384:     // error in the case where the action was also associated with a
Chris@384:     // toolbar button. But that has the unwelcome side-effect of
Chris@384:     // removing the shortcut hint from the menu entry. So now we leave
Chris@384:     // the shortcut in the menu action as well as creating a global
