An an addendum - I went to "system settings"/"keyboard shortcuts" and tried changing the "Move between windows, using a popup window" command to a different key combination (I selected alt-T). When I did this, alt-T also did nothing. Then I switched the binding back to the default alt-tab. It still did not work.
So it looks like there is nothing magical about alt-tab. It is a problem in the "Move between windows..." command; it simply does nothing when its key combination is pressed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/652097 Title: alt-tab does not switch between applications -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
