Ed Bot over at ZDNet has a list of some cool shortcuts for Windows. These are mostly for Windows 7 but may work in Vista and XP as well.
"The shortcuts I’m referring to involve the shell command, which is curiously undocumented in the Windows 7 Help files or on Microsoft’s web site. The idea is to give Windows programs and users access to common locations using the Windows shell, Windows Explorer. The syntax is simple—you type shell, followed by a colon and the name of the shell folder location. That list of folder locations is hard to memorize, with lots of inconsistencies especially in regard to spacing. For example, the shell shortcut for the shared Downloads folder is shell:CommonDownloads, whereas the equivalent shortcut to the shared Documents folder is shell:Common Documents. And the command will not tolerate typos. If you add a space in the former or leave out the space in the latter, the shortcuts won’t work. The good news is that these commands are not case-sensitive, so you can ignore the sometimes odd capitalization.
Despite the syntactic challenges, these shortcuts are very useful for some tasks. They’re especially good for fast typists who don’t want to move their hands from the keyboard to do a bunch of mouse movements. If that’s you, tap the Windows key to open the Start menu with the insertion point already positioned in the Search box. Then type shell: followed by the location."
