feature request: keyboard shortcut for cycling through workspaces

Just like Alt-TAB is used to cycle through windows, we could have a key for cycling through workspaces, in last-visited order. KDE has this option, and I usually set it to Meta-TAB, which complements Alt-TAB very well. This is very useful for people having a big number of workspaces.

At least I haven't found such an entry in the keyboard shortcut list that appears under

• Window Manager Settings -> Keyboard tab
