I made a "key pressed?" block that can report values that aren't in the normal "key pressed?" block.
For example, in the normal "key pressed?" block, there isn't a "Alt" key option, "Backspace" key option, "Enter" key option, "Tab" key option, or "Shift" key option. So I added them in. You don't need to give me credit if you want to use this block, but it is recommended.
@sirhopsalot I think this would be good for starting a speedrun timer for your competition.
Iv'e already created this in my custom blocks collection.
Oh. I wished someone told me that...
Also you cant do escape because escape stops all scripts.
In my custom blocks project I added support for the control key.
