Ctrl+shift+h

Other way to do this is, just press scroll of the mouse, (Scroll works as middle button as well as scroll), you will find four directional arrows, you can move mouse in the direction you want it will flow in that direction more you move more it will be faster !!!

In case of working with laptop, where we cant take the mouse along with it. More over a key board short cut could be used very faster than using mouse..

Thanks for your addition 

Thanks. Keep Updating.
