Unable to map gamepad inputs and keyboard keys in the same macro?

[dotaxis]

Please install the newest version from source to see if the problem has already been solved.

Quite simply, I would like to be able to do this

if_tap(
	key(KEY_Q),
	BTN_B,
	timeout=250
)

But it doesn't seem to be supported. I can't use keys and buttons on the same macro.

Are there plans to support this in the future or am I doing something wrong?
