Question about button selected state

[pucedragonlord]

I'm curious as to what all makes a button appear in the selected state and what doesn't. From what I've found so far, having a normal variable match a button's action does, but something like opening a menu with a button or changing a tooltip on click doesn't change the state. How exactly do these buttons decide whether they should be in the selected position or not?

I ask partly out of curiosity, but partly out of wanting some menu buttons to stay highlighted when they show parts of a screen or open a menu. I suppose I could attach a bunch of variables to them, but I've had trouble with variable scope and screens before, and it seems silly to have a bunch of variables that are only used to toggle button states.

I got a good explanation on this here:

neat, looks like I'll be defining some custom actions.

It doesn't mention show or show menu, though. Any idea if either of those have any sort of selected behavior, or are they meant to always leave things unselected?
