Lesser known Windows 7 tricks

Hey guys, so yesterday while working on my desktop with Windows 7, I accidentally clicked the scroll wheel on an icon on my taskbar and it opened a new window in that program (there were already a couple of windows open).

I was totally unaware of this feature and I found it to be a pleasant surprise. Instead of going to the Jump List to open a new window in an opened application, I can just click the scroll wheel.

Anyway, I'm just writing this post to see if anybody else wants to share some lesser-known Windows shortcuts or tricks. I would personally love to learn them and I'm sure others would too!
