It would be very convenient (at least to me) to have a zone in the transport window in which a left click toggle Play/Pause while a right click Rewind completely the track. This would be usueful since with only the buttons and without moving the mouse one could play/pause or rewind. I have modify my mouse so that I can click with a pedal.
Also keyboard short cut would be useful in combination with qjoypad.
Thank you !
I solve the problem using xdotool and mapping the rosegarden buttons to the buttons in my own window. I can give the python script (which use xdotool and tkinter).
