bind held key without blocking typing

I have a foot pedal that I would like to toggle a file's contents when pressed and released. I have got the foot pedal acting like a normal key with a keycode and disabled it from repeating with xset -r . But when I bind it to a command with sxhkd/xbindkeys they block me from typing while it is pressed. I need to be able to type while it is pressed. sxhkd:

F25
	echo dictate > ~/mode
@F25
	echo command > ~/mode
