Steps to reproduce the problem:
1. Use US Extended Keyboard
2. Press Ctrl+Alt+/ (or ?)
3. Press AltGr (right Alt)

What is the expected behavior?
It should show AltGr shortcuts when AltGr is pressed

What went wrong?
It's showing regular Alt Shortcuts, which doesn't work at all (like AltGr+Left being back, that's not true).

I'm pretty much guessing with what the AltGr mappings are since there's no explanation.

Did this work before? No

I use AltGr to input characters sometimes like áéíóúñÑ. There's another issue already listed about AltGr+Left not working, but it's unrelated to this.
