2023-06-22 (Th) KeyBoardolier Retaining keys

I wanted to have a function key that would allow me to type letters irresponsibly fast. When I pressed the third function button, the program would send a keystroke to any button currently depressed, but with the cycle times I saw, it was faster just to hold the key. The only advantage to sending the keystrokes explicitly like this was that I could send multiple keys at once, like JOYJOYJOYJOYJOYJOYJOYJOY. I tried sending five copies during each program iteration, but even that was too slow, so I ignored it for now.

I moved onto the retained-key function, an idea I had long ago. I built one of my first keyboards with latching switches for the arrow keys so I could scroll through long web pages without holding the button. I liked the function, but it took a lot of space for the extra buttons, and I updated this idea to include a mode that would ignore any button releases. Creating this mode was simple because I instructed the program to press keys like it was operating in mode0, but when it was time to release, I did nothing. The escape key releases all buttons in this mode or mode0.
