Quickly Select the Startup Disk on the Mac OS X Desktop

Want to quickly find and select your boot disk amidst a variety of other internal and external drives? Just hit Command+Shift+↑ (Command + Shift + Up Arrow) to immediately choose the startup drive on the Mac OS X desktop from anywhere in the Finder.
This command is what the Go To Parent folder shortcut turns into when you hold down the Shift key, which is appropriate given the startup disk is the ultimate root directory to anything else on the boot volume.

So, using this shortcut I can select my Boot Camp partition without having to select it from System Preferences?
No, if you have your Hard disks visible on your desktop use this shortcut to select it in the Finder. This really doesn’t do anything if the Hard disks are not visible.
Use something like Quickboot (free) to easily boot into Boot Camp without going to the System Preferences.

I don’t get this hint either and it is not working for me.
This does not work on my system. Does it not work with BT keyboard?
It doesn’t change your startup disk, just highlights it on the desktop so you know which one it is.
Once menu drops down, just pressing the shift key brings up the start up disk choice.
