Earlier while I was designing my printed portfolio, I came across the problem of not being able to use capital letters. I contacted my friend Scott Detweiler to see if he knew a solution since he's both a software guy and a Photoshop expert.
He said on some Windows keyboards (I'm using a Windows keyboard on a Mac) there is a piece of hardware called the "A20 gate" that can sometimes get stuck. The solution is to tap the Control, Capslock, and Tab keys all at once a few times. It ended up releasing them and I was good to go!
Just wanted to put this out there for people to find in the future because it was a pain not finding any articles about this.
