is there a shortcut for toggle between default screen layout and composit screen layout? i click a lot on the two screen layouts , composite and default. 
every click that i do often,  i try to find a shortcut for it. 
but i doubt there is a shortcut for screen layouts ?
i have not seen a Phyton code showing up at these places.
or am i missing something ?
is there a way to get this shortcut ?
in the worst case i will just keep on clicking each time. 
 but i prefer the shortcut.
i hope anyone has an answer, thanks.
Yes, press Ctrl+Left Arrow to go to composite from Default, and Ctrl+Right Arrow to go back.
