This is more a personal reference than anything, but hopefully someone else will find it useful too. In Vista you can navigate to many of the system folders, such as the "Send To" folder by typing shell:<Command Name> (eg shell:sendto) in the Start/Search(aka Run) text box (See screen shot). This sure beats typing C:\Users\[UserID]\AppData\Roaming\Microsoft\Windows\SendTo\ to do the same thing.

This tip works for many of the folders and other system screens / apps. Take a run over to EdHolloway.com! and check out the list of Shell Shortcuts in Windows Vista
