Press key and release (DigisparkKeyboard)

[b4zz4]

I try to do a piano and joystick (for games with keyboard) with digikeyboard and need "press keys" and release it.

Same problem other application
I want to program a PTT key (push to talk),
So I need some kind of

DigiKeyboard.sendKeyPress (KEY_F10);
DigiKeyboard.sendKeyRelease (KEY_F10); // release specific keyy
DigiKeyboard.sendKeyRelease ();  // release all pressed keys

instead of a
DigiKeyboard.sendKeyRelease(KEY_F10);
function

btw. is it possible to use higher function key value as example F13 to F24
some industrial keyboard have some of these
