I have a media center with a keyboard but no mouse. Is there a way I can navigate the Unity Greeter with a keyboard so I can change the session I log into, etc.?
So far, it would seem you can 'navigate' the options using the Tab key, and confirm with Enter/Return or the Spacebar, but this is a bit wonky doesn't work very well yet.
Ctrl+S activates the Screen Reader while Ctrl+H activates the High Contrast display.
