Ubuntu: switch between windows of the same application
If you are on Ubuntu with Unity, pressing Alt+Tab toggles between applications only normally. So if you have more than one browser or terminal window open it’s somewhat more difficult to switch between those as compared to good Windows. At least until you figure out how to do it.
I did find this quite annoying and resorted to either clicking the application icon in the left task pane and then selecting the appropriate window, or quickly hitting
Alt+Tab followed by
Alt+Shift+Tab which toggles the windows of the same application as well.
Not really satisfied with that I asked the mighty internet and sure enough discovered the solution: Simply press
Alt+[key above tab=^]. For me on a German layout it is
Alt+^. I am using Ubuntu 13.04. Source: http://askubuntu.com/a/343723/202942
