Ubuntu has a cool feature that lets you click and drag a window by clicking anywhere in the window as long as you are holding down either the Control, Alt, or "Win" key while you are dragging.

It's difficult to show a screenshot of dragging the window, and we haven't quite gotten to the point of doing videos on here yet, but we'll give it a shot.

First, you can configure the settings by going to System \ Preferences \ Window.

In the "Movement Key" section, you can select which key you want to use for the dragging. Now that you are on this window, hold down the Alt key and then click in the window anywhere, and move your mouse.

You will see that the window drags easily. Once you get used to this, it's a great technique for moving a window easily without having to aim for the title bar.
