Add the Steam overlay to Starcraft 2:
* Go to your Library
* Click "Add A Game" in the bottom left corner
* Wait for your apps to load and add Starcraft 2
* Now that it's in your library, from steam right click on it and add a desktop shortcut
Now when you start Starcraft 2 from your desktop shortcut you can use the Steam overlay (shift+tab).
