One of life's great mysteries...solved!

A Microsoftie explains one of the things that, even after all these years, I still never really understood about Windows -- until today, that is:

Will dragging a file result in a move or a copy?

- If Ctrl+Shift are held down, then the operation creates a shortcut.
- If Shift is held down, then the operation is a move.
- If Ctrl is held down, then the operation is a copy.
- If no modifiers are held down and the source and destination are on the same drive, then the operation is a move.
- If no modifiers are held down and the source and destination are on different drives, then the operation is a copy.

Call me stupid, but this behavior, part of Windows since 1989, was news to me.
