Bug Description

unity 3.6.6-0ubuntu1, Ubuntu Natty
unity 4.8.0-0ubuntu2, Ubuntu Ocelot

1. Open the Dash.
2. Press Alt+Tab.

What happens:
* In unity 3.6.6-0ubuntu1, nothing happens.
* In unity 4.8.0-0ubuntu2, the previous window is raised behind the Dash, but the normal Alt+Tab display does not appear.

What should happen:
* The Dash disappears.
* As long as the Alt key is still down, the normal Alt+Tab display appears.
* When the Alt key is released, focus switches to the appropriate window.

With unity 3.6.8 at least the TAB-key gets interpreted for walking the icons visible in the dash. Does that at least work for you?

macslow: urm, I think it still stands. Something, while the Dash is open, is eating the Alt-Tab keypresses and not allowing them to be processed.

My suspicion of what should happen is:

  1. The normal Alt-Tab processing should immediately respond.
  2. Dash, no longer being the foreground window, should hide itself.

I can confirm - alt-tab should cycle through windows per usual, closing
the dash along the way. The dash should not appear in the alt-tab list.

Alt+Tab unfortunately does nothing for me in Unity (same with Alt+Esc). I've desperately searched for a task selector indicator or something, but currently the only way to switch between (maximised) tasks is using the Dash menu.

OK, seems a Compiz setting was disabled by default, and enabling it gave me back Alt+Tab; however, something is preventing me setting the other familiar shortcut, Alt+Esc. Here is as much info as possible, including the fact that 2 settings seem to be identical, even though they should behave differently:

Go to CompizConfig Settings Manager > Window Management, and enable Static Application Switcher; if that doesn't work, click on that plugin, and set the desired "binding" to Alt+Tab in the Bindings tab. It should work once you've enabled that plugin, though, but if you click on it to see its settings, don't be surprised that the keyboard shortcut for "Next window" is <Alt>Tab, even though it is actually "Next window (All windows)" (which is probably set to <Control><Alt>Tab) which pops up the window list. Setting "Next window" to <Alt>Escape will not automatically move you between open windows, as you'd expect, but seems to do nothing; yet, if you set it back to <Alt>Tab, it will once again show you all open windows (as will <Control><Alt>Tab).

So I got Alt+Tab back, but I actually use Alt+Esc more, so wouldn't mind getting that fixed now! Cheers
