Just to go out on a wild tangent...

buttons on simple hardware devices usually have many many functions.

this button has a function. but if you are powering up and hold it, it does a different function. press and hold this button and while holding it press another button for something else.

The most extreme example of this kind of thing I can recall is the anduril open-source flashlight firmware: an enormous number of functions on a one-button flashlight.
