Quickly Change Windows Using Scale And Hot Corners
Whatever make of netbook you have, you’ve got a tiny screen (typically only 1024×600 resolution) to make the most of.
We’ve already look at using window previews to quickly switch between open applications. But, as the saying goes, there is more than one way to skin a cat, so today I’m going to show you how to use the Scale plugin for compiz to switch between open applications using a hot corner.
Pre-requisites
To use hot corners, you must first have switched over to using compiz on your netbook. If you’re not sure how to do this, we have a complete set of instructions for you 
You’ll also need the CompizConfig Settings Manager (ccsm) installed. To install this, open up a terminal, and run the following command:
sudo apt-get install ccsm
Enabling Show Windows Hot Corner
Launch ccsm (you’ll find it under the System menu, as Preferences -> CompizConfig Settings Manager). A window will open listing all of the different features of compiz:
CompizConfig Settings Manager
All of the different features are grouped by type, and the list of types can be seen on the left of the window. Click on Window Management, and on the right hand side of the window you’ll see a bunch of features appear, including the one we are looking for
The Window Management Group In ccsm
Click the checkbox next to Scale to enable it, and then click on the word Scale to go into its settings.
The Scale Options In ccsm
Scroll down until you see the Initiate Window Picker For Windows On Current Output option. There should be an icon to the left that looks like a computer monitor, and a button to the right that probably says None. Click on the button to the right, and a window should pop up where you can choose which corners you want to use:
Choosing Hot Corners For The Scale Plugin
I prefer to have both the bottom corners for this feature to reduce how far I have to move the mouse, but of course you may prefer a different choice.
Click Okay, and Scale should now be active.
Try it out for yourself. Move your mouse to your chosen hot corner, and your open application windows should appear. Click the application you want to use, and that window should now be the one in front.
