Everyone knows what a hotkey is. They're keyboard shortcuts that help you be more efficient, and they come in particularly good use in real-time strategy games like the new StarCraft 2: Wings of Liberty video game.
This two-part video tutorial will give you a quick guide to using hotkeys in StarCraft 2, but it is very important that you learn your own style of hotkeys, because for everyone it's different. This is just to get you started, to show you the basics of hotkeying.
This game uses the Beta version, but Wings of Liberty is out NOW!
