Q: I just made a horrible mistake and deleted an important chunk of text from my document. Do I have to retype the whole thing over again?A: Undo it. We all make mistakes and then need to correct them. One of a computer's best functions is that it allows us to undo or take back a mistake. You undo by either going to the menu to select "Edit" and then "Undo," or else use the handy keyboard combination of CTRL > Z - that is, hold down the CTRL key while clicking the letter Z. This is a standard feature of nearly all Windows functions and programs. For example, I have highlighted text to change the font and then forgotten to deselect it before I began typing again.
