Hi guys. I am making a HTML editor and using costumes to represent text. I am wondering, why won't scratch use capital letters even though the other shift characters work?

Making this Project

I added the list of all letters and characters, even Capital.
These letters included: ABCDEFGHIJKLMNOPQRSTUVWXYZ.

Scratch isn’t case sensitive in anything exept costume names. So key detectors cant detect whether the key you pressed is capital or not.
