Comment 27 for bug 998285

I agree this is quite annoying and unintuitive. But from what I'm seeing in 16.04, there is no more alt-` by default and the action is back to MS Windows with a simple Alt-tab behaviour which switches between the two last used windows of any app. Then at some point Ubuntu expanded upon that to have alt-tab switch between last used apps and alt-` to switch between last used windows within an app. But now it seems they have decided to backtrack to simplicity causing users to have to yet again re-condition their behaviour which is really frustrating.

There really should be an option for either behaviour. I can't see any options to change this behaviour in the tweak tool or unity plugin in CompizConfigc (ccsm). There should be a third entry in the windows switching shortcuts as "Flip through applications in the switcher" then people can pick to assign alt-tab to that one or the default "start switcher".
