	You can also edit keybindings there.
	
	Mod4 is super key, on many keyboards marked with windows logo.	
	As a rule of thumb, super+direction moves focus, 
	super+shift+direction moves focused window,
	and super+ctrl+direction resizes windows.
	
	Arrow keys, wasd and hjkl represent directions and numbers represent
