Description Arkadiusz Ryszard Świętnicki 2025-07-01 15:41:26 UTC 
SUMMARY
The Orca Screenreader incorrectly binds modifier keys to structural navigation keys on websites

STEPS TO REPRODUCE
1. With Orca enabled, open any website with Mozilla Firefox or Chromium.
2. Press Orca Key + H to turn on learn mode
3. Press modifier keys by thgemselves (left CTRL. left shift, left alt, right control, right shift, right alt)

OBSERVED RESULT
Below is the list of bindings Orca ssigns to those actions
- Left CTRL: goes to the last live region that made an announcement
- Left Shift: Go to the next image
- Left alt: goes to the next button.
- Right shift: Go to next combo box.
- Enter: go to next table.


EXPECTED RESULT
Modifier keys, by themselves never had actions bound to them. I expect the modifiers, especially shift to behave like it always did, allowing m to reverse structural navigation.
