Steam browser protocol

There are numerous system-wide commands available that interact with Steam. All of them open up Steam if it is not open. They can either be typed into a command box (Start-> Run) or through your browser's address bar (you can normally create links to them as you would web page links). Use a Steam Application ID in place of <id> (i.e. 211 for the Source SDK).
