Over on the Windows Vista Team Blog, Nick White has posted some keyboard shortcuts for Vista users. They are :

Ctrl+Esc — Opens the Start menu
Windows Logo — Opens the Start menu
Ctrl+Alt+Delete — Displays LogOn screen including Lock Computer, Switch User, LogOff, Change a Password and Task Manager
Print Screen — Copies the full screen image to the Windows Clipboard
Alt+Print Screen — Copies the selected window’s image to the Windows Clipboard
Alt+Double-Click — Displays property sheet for the selected item
Alt+Enter — Displays property sheet for the selected object
Shift Hold — when loading disk to prevent AutoPlay application
Shift+F10 — Same as right-click
Shift+Right-Click — Shows alternative commands for the selected object.

Nick invites others to contribute to the list and there are lots more in the comments section.

Worth trawling through them, I think.
