Slight clarification: The paragraph reading "If I change the keybinding to Ctrl+AudioPlay (or shift, or any other modifier or combination of modifiers), it works as expected: music starts and stops on the press of the "Play/Pause" button."
should read: "If I change the keybinding to Ctrl+AudioPlay (or shift, or any other modifier or combination of modifiers), it works as expected: music starts and stops on the press of selected combination of modifier(s) + "Play/Pause" button." Martijn
