My request for a new feature starts with a simple question. Why when I set the quick command to turn off the SOLO or turn off the OVERLAYs I have to indicate which input? I understand for switching on, in that case it is necessary to indicate which input to enable, but to switch it off it is not necessary.
For overlays, an entry such as, current or last is missing from the list of possibilities, to enable, with a quick key, the last input chosen on the desktop screen. This command would be an exact copy of the mouse click. Thank you

Thanks, I know this command, for OVERLAYS I was referring to ACTIVATORS.

In truth I have to correct my request, the problem of assigning the input to the quick key exists only for the SOLO function.
While it would be very useful that in the list of ACTIVATORS for overlays, there is also a CURRENT entry, without necessarily indicating the input.

Summarizing my request:
1) Quick key to set the SOLO to OFF without indicating the input (not is necessary)
2) Quick key to turn ON / OFF the 4 OVERLAYs individually, and use the last selected input. (as happens with the mouse click in the area below the transitions)
3) ACTIVATORS the LED lights up when the overlay is ON without necessarily indicating the input

I apologize if I was unclear before
