Thanks. The only thing I would like to have added is either a sound when the function keys are pressed or make them light up, so you know for sure that you pressed it. But, I'm getting a little better at making these trainers, so I will add that feature to the next one.
I'm also trying to learn how to make multiple tabs/pages in trainers so I can add more functions while not taking up a lot of screen space. I wanted to make this trainer just a little bit smaller, but I tried that and beyond a certain point the text was just too hard to read, so I had to settle for this size.
