Came across a page that lists up alot of useful tricks in Windows 7: Windows 7 Secrets
Especially shortcuts with keystrokes:
- Win+1…9 = 1…9 applications in the taskbar
- Win+Shift+Left/Right = move window over to the other screen at same location
- Win+Home = Minimize all other windows
- Win+P = Multi monitor setup (duplicate, extend, etc)
