In Windows if you are in a program and press `Super`+`←` for example the program would take up half of the left side of the screen. Extremely useful when wanting two programs to sit side by side.

`Super` key being the special key in Linux then. And the `←` being the arrow left key.

What is the Ubuntu version of this? I have no idea what this is *called* and hence my Google results have come out with no result.
