I'm using Xubuntu 14.04 and I want to change the Alt+Tab behavior. In Xubuntu, it just has the option to alternate between applications, but I prefer something like Gnome Shell or Unity, that have the Alt+` to change between windows of the same instance. This is possible?
I found that option among commands that you can assign the shortcut to in Window Manager Settings via Whisker menu → Window Manager → Keyboard → Switching between windows of the same program. (Translation mine, so official one may vary.)
In my case it's Super+Tab, but I think it was empty by default.
