At any point you can undo , or reverse, your most recent edit or edits. Click the toolbar's Undo button. (This performs the same action as selecting Edit, Undo and is easier to use in most cases.) If you delete a character or even an entire paragraph, for example, click Undo. Word puts the deleted text right back where it was originally!
Word keeps track of multiple edits. Therefore, if you realize that the last three modifications you made were wrong, click Undo three times and Word reverses those three edits no matter what they were. If you reverse too many of your changes, just click the Redo toolbar button, and Word replaces the undo ”in effect, undoing the undo! It gets confusing. If you click the arrows next to either the toolbar's Undo or Redo buttons , Word displays a list of as many as 100 or more recent changes, which you can choose to undo or redo as a group from that point forward.
