(Resolved) Continue running one part of code while still checking other inputs?

AWOL:

His app seems very simple, why not try using the Bounce library befoe going to an ISR?

That's what we've been trying to persuade him/her to.
The message doesn't seem to be getting through.

That's the first mention of a bounce library right there (which is a huge pain in the ass to actually find, BTW. For all the mad coding skills here, this website's search feature sucks.) But now that I have it I'm trying to give it a shot. Probably because I just don't know of the possibilities, but I can't see how this helps me. Is there a Bounce Library Tutorial? Everyone references using the Bounce library, but I cannot for the life of me find anywhere that explains how or why Bounce works (other than keeping a button from chattering when pressed). Thanks y'all for the help; maybe one of these weeks/months I can find my answers.
