Prior to upgrading Ubuntu from Meerkat (10.10), it was possible to put windows on the left or right of the screen using Ctl-Alt-4, Ctl-Alt-6. Subsequent presses of the same would resize the window from the respective edge outwards. Needless to say that the feature is mandatory for mouseless window management (try pressing Ctl-Alt-5 several times to see how useful it can be).
I've checked Compiz settings where Window Management/Grid contains the relevant configurations. However, I cannot see anything related to cyclic resizing (window placement width).
How can I re-enable this functionality?
