Arrow key window selector extension.

[privacy <privacy tanwald net>]

Hello,

I have written an extension for selecting windows in overview mode with 
arrow keys. When you are in overview mode and press an arrow key, the 
most recently focused window will be selected and highlighted. As soon 
as you have navigated to the desired window you can press ENTER for 
activating the window or DELETE for closing it. Mouse events and other 
key events will terminate the selection process. I think the navigation 
logic should work with any window placement strategy and multiple 
monitors should also be supported.

You can find the extension here:

I would be glad about some feedback, ideas for improvement and please 
report issues.

Cheers, Paul
