2 Keybaord Shortcuts for Macintosh

 Here is an addition i get from Bob Mathew

That's a good list as far as it goes. It would be unrealistic to publish a fully comprehensive list of shortcuts, but notably missing were some of my favorites:

• Shift+Arrow (left or right) -- Selects text & objects in the direction of the arrow you press
• Shift+End -- Selects from cursor position to end of the line
• Shift+Home -- Selects from cursor position to beginning of line
• F12 -- Save As
• Windows Key+E -- Windows Explorer (aka, "My Computer")

And, two that are limited to Windows 7:

• Windows Key+Left Arrow -- Re-sizes current window to fill the left half screen
• Windows Key+Right Arrow -- Re-sizes current window to fill the right half screen

These last 2 are really useful on widescreen monitors when you're having to switch between 2 windows, and are working in both.It may also be useful to point out that it's not necessary to use the utmost finesse, thereby releasing both or all 3 keys at exactly the same time. In the case of Ctrl+Alt+Delete, for example, press and hold down the Ctrl and Alt keys, press and release the Delete key, then release the other 2.
