Hi everyone! This is a system that lets you detect more than just letter and number keys. It works by cycling through a list of alphanumeric characters (eg. ! @ # $ % &) that includes letters, numbers, and symbols. Then, when a key press is detected, the key is saved to a variable. This works for all keys except for functional keys like Control, Shift, Backspace, and a few others. I used this system to make a typing demo where you can type text onto a laptop without using input blocks. Try it out yourself and use the enter key to erase the text! If you want to use this in your own projects, simply backpack it and add it wherever you want, and if you want to be able to detect more characters (possibly from other languages), just add more characters to the list!
I didn't invent this system; it has already existed before but I don't know who originally created it.
