i'm using stat(30) it works fine it shows the keys but it returns " " when i press backspace,space,ctrl,shift is there a way to get these keys press status?

Backspace - '\b'
Space - ' '
Ctrl/Shift - these don't register as keypresses in webplayer at all. (a way to query these as modifier keys would've been nice...)

Also of interest:
Escape - '\27'
Enter - '\r'
