Keyboard shortcut for restoring applications from the Mac OS X Dock?
Command + Tab until you get the app's icon.
Before releasing the Command key, press and hold the Option key.





You must switch to another app and let it take focus first. In other words, you can't just Command + Tab to another app and before actually selecting that app (by releasing the Command and Tab keys), switch right back to your minimized app, which you might attempt to do if you minimized it by accident or just simply changed your mind shortly after minimizing.
Both the Command and left Option keys must be pressed on the same side (left or right) of the keyboard.
