Open Microsoft Word and type something in a document, then Press Control Z, ...what happen !
CTRL-Z is normally used in
word processing documents, but it also works just about anywhere in windows.
Let's say you accidentally drag an icon to your desktop and really wish you had
it to do over. Well, hit CTRL-Z
and the icon vacates your desktop and jumps back to wherever it was before.
Works with Windows Explorer too. Let's say you accidentally delete a file. Instead of going to the recycle bin to recover it, hit CTRL-Z. Note that this only works if you are sending the file to the recycle bin. If you hold down the SHIFT key while you delete (bypasses the recycle bin) the file is lost. All the CTRL-Z ing in the world won't help.
