How to preview windows of a specific application in Unity?
In Windows 7, if you have more of the same window open at the same time and you click on the icon, it pops out a preview-list of all the windows.
Is there anyway to achieve the same thing in Ubuntu 11.04? See below:
Yes, you'll find that behavior available with Unity as well. Launcher icons will have multiple small arrows to the left of them when multiple windows of the same application are open. Click that application's icon again to change between individual windows.
You can edit the behavior of this and many, many other Unity/Compiz desktop settings using
CompizConfig Settings Manager
(ccsm), which you can find in theUbuntu Software Centre
.
