AltGr + q does not insert /

[malbarbo]

Using Windows 10 and pressing AltGr + q inserts / in any application, except in DrRacket where it triggers undo.

On Linux AltGr + q works fine on DrRacket and inserts /.

Here is the output of running https://github.com/racket/gui/blob/master/gui-test/tests/gracket/showkey.rkt on Windows 10 and pressing AltGr+q

I'm experiencing the same thing on Windows 10. My keyboard layout is ABNT-2.

A workaround for this is using PowerToys' Keyboard Manager to override the AltGr + Q shortcut to output a real / instead of relying on DrRacket to do that. You can even restrict that remapping to just DrRacket.
