Keyboard shortcut to return to standard Step-entry mode from f.i. Re-pitch mode

When entering passages for different instruments, I find the re-pitch mode (short-cut ctrl.-shift-I) to be very usefull. However it would be very nice if there would be a keyboard short-cut to return to standard step-entry mode when needed. Possibly by using the ctrl.-shift-I to toggle between re-pitch and back to step-entry again. At present we have to use the mouse to do this, which for me disturbs the workflow a bit. Being able to toggle back to step-entry from re-pitch using keyboard shortcuts would be a nice feature.

I have search under preferences and keybindings in order to set this up myself, but unfortunately the re-pitch and step-entry modes are not listed here.
