when green flag clicked
forever
set [ test] to <key  (join [1] [] )  pressed?>
end

This code may be glitched if you hold the 1 key then hold the shift while holding 1 then release both.
I did this and it kept saying true until I clicked 1 again

It thinks you are pressing the “!” key, not the “1” key.
It makes perfect sense, because if you hold down shift and 1, it makes !
I doubt this is a bug, but just a feature.
