Here's another way to open your website via Window's keyboard command instead open it the normal way from your favorites menu. It will save you time, if you can remember these unusual commands.
Goto IE, favorites menu and highlight your favorite website you want to create a command to launch quickly. Now with your mouse hit the second key and choose properties. You see something like
ctrl + alt +g for opening google.com. Now open up a new Windows in IE and type the same commands to open google.com.
