You'll need to turn your event into an 'Or' block. Move your other conditions -- the overlapping check, value compare, what have you -- into a subevent of the keyboard event. Add your touch condition to the keyboard event, then, right click the event and click Make 'Or' block, and your event will now check if either the keyboard or the touch condition is true. Move your actions into the subevent where you check your other conditions and you're good.
