See how many keys your keyboard can detect at once. Shift+character supported. Try this in TurboWarp - Many more different types of key presses are detected! E.g. "delete"... https://turbowarp.org/725189322 Note that "Alt Gr"+character doesn't work properly - Scratch never detects when it's been released and to fix this you'll need to reload the page. (However these do work in TurboWarp!) If I've missed any keys let me know!
