Detect which keys are pressed!
Press keys. Voilà!
Apparently Scratch can only detect 8 key-presses at once.
To use: Drag the sprite into your backpack then into your project to. You must use this block with this sprite as the list has names of the keys.
If, in your project, it's not working, click the green flag and try again.
Sadly, I don't think it works with keys like shift, control, etc.
