Over the years I have found out a good bit of shortcuts, all of which make using Windows that much faster and easier. I was wondering if I had missed any important ones, or ones that just saved any time. I tried to keep these relative to Windows only, as programs such as Mozilla, Photoshop, etc. bring in hundreds of other shortcuts, which do not apply to all users. These are the current ones I know:

For the mouse:
Scroll wheel       - opens a link in IE into a new tab
                   - closes a specific tab in IE when closed on
Right click-n-drag - nifty menu to make a copy of a file or create a shortcut

For the keyboard:
Cntrl + Alt + Del  - need this be explained?
WinKey + R         - opens 'Run..'
WinKey + D         - shows the desktop
WinKey + E         - opens 'My Computer'
WinKey + F         - opens 'Find..'
WinKey + Tab       - cool way to switch inbetween windows
WinKey + L         - locks the computer

Alt + Tab          - switches windows with a simple interface
Alt + F4           - closes windows
Alt + F            - opens 'File' (Handy for things like IE if you have the menubar disabled)

Cntrl + F          - find text on current document
Cntrl + W          - closes a window, or current active tab in IE (or IE itself if only one tab)
Cntrl + C          - copies selected text / image
Cntrl + V          - pastes selected text / image

So does anyone know of any more shortcuts that just make life easier? I would be much appreciative of any, and I am sure that some other users would like to know some too =]
