Expose on the mac and I forget what its called in Unity but its pretty cool for checking out running programs and switching between them easily.
On Lubuntu there is no compositing which makes this feature basically impossible... Luckily Skippy XD does the trick. How? It throws up a quick compositor when you activate it to get the job done, then closes it when your finished selecting what you want. So no resources wasted.
Pretty easy to do..
Download and install SkippyXD depending on your platform from here
Once installed open up run or a terminal and enter
find the line
below it copy and paste the following
*****Updated code to correct syntax error, code above is updated*****Code:<!-- Start Expose for LXDE--> <keybind key="A-grave"> <action name="Execute"> <command>skippy-xd</command> </action> </keybind> <!-- End Expose for LXDE-->
save and close
open run or a terminal and run following command
now when you hold the alt key and hit ` you expose feature will activate
