ALT+Tab in keynav mode brings up HUD

[Alan Pope 🍺🐧🐱 🦄]

Test Alt+F1 KeyNavMode Shortcuts
-----------------------------
This test shows that all the shortcuts work and also exits from keynav mode.

1. Press Alt+F1 to enter keynav mode
2. Press Super + a
3. Press Esc
4. Press Alt+F1
5. Press Alt + Tab <---- this bit fails
6. Press Alt+F1
7. Press Ctrl + Alt + t

Outcome
  The first shortcut opens the dash app lens, which it should open it and quit the
  nav mode. The second shortcut switches between applications. The last one will open
  a new terminal. This is to show all SUPER, ALT, and CTRL shortcuts work; while
  closing the keynav mode.

-------

Step 5 fails. I get HUD instead of alt-tabbing. Here's a video showing it.

For me the Alt + Tab step normally exits the keynav mode, HUD only appears when I do a really fast Alt + Tab tap. But that's probably what Alan has in mind.

[Sebastien Bacher (seb128)]

is that still an issue?

[Sebastien Bacher (seb128)]

seems it is...

[Alan Pope 🍺🐧🐱 🦄 (popey)]

Yeah, still does it here on two separate machines.

[Alan Pope 🍺🐧🐱 🦄 (popey)]

Still broken on ppa:unity-team/release. Also brings up HUD when doing ALT+`

[Brandon Schaefer (brandontschaefer)]

I can confirm this not working with trunk unity.

Not really a 1210b1blocker, as it is not a regression - it's something we know about well.
