Hello! Long time user, first time on this list! I have looked through xmonad contrib and google for the ability to toggle to the last window, but haven't found it yet. The exact behavior I am looking for is something that traditional window managers do- Alt+Tab on Windows. This is most useful for smaller screens where all the programs are maximized so that unfocused programs are hidden. I have a workspace with 3 windows: A, B, C ..., and a is focused. I switch focus to B. I would like a shortcut to switch focus to the previous focused window (in this case A). If I use that shortcut again I will focus to the previously focused window (window B). I could go back and forth over time and never even notice window C. ideally with Alt+Tab holding down Alt (Alt+Tab+Tab) would reach window C. Is there an extension for this already? If not, can someone give me a pointer to how I would implement this? I am also interested in a similar ability, but for switching between workspaces. Thanks, Greg Weber
