Letters shouldn't be able to be typed when ctrl is pressed

I was confused for a bit cause I kept getting J's in chat, but it happens when closing dev console with ctrl-shift-j (I don't want to preventDefault this).

After checking how it works on java (225 deob and danes 317) it seems that you can't type letters if ctrl is pressed, e.code is correct but e.value changes with ctrl pressed.

Side note:

        if (CANVAS_PREVENTED.includes(key)) {
            // prevent canvas from using tab and other blacklisted keys. no function in 225?
            e.preventDefault();
        }

Were these keys blocked in 04? I agree that it's a good idea though.
