not sure what you're asking, but by default super can change the page layout.
Super + left/right arrowswitch workspace
super + down arrowview windows in current workspace and shows workspace interface.
super + up arrowToggle full-screen
ctrl + super + left/right arrowwindow to left or right half of screen
shift + super + left/right arrowmove window to different monitor (if you have more than one)
super + ashow all windows
Hopefully this answers your question, but if not what behavior are you actually trying to customize?
