|When you let orca pass the next key to the actual application (Orca+Backspace by default), orca key gets stuck and other keys behave like if Orca key would be still  pressed. You have to press Orca key again to fix this.
How to reproduce:
1. Press a keybinding to let the next keypress through orca
2. press some key - for example S
3. The key gets passed correctly.
4. Now press S again - you will be toggling orca speech, but you aren't holding Orca key. Try other keys, and the behaviour will be the same.
5. Press Orca key once and keys will start working properly again.
This is quite anoying, because for example when using Google calendar, you need to pass some keys to the Firefox - Google has prety neat keybindings for calendar by the way.
