One question I often get from others who are frustrated with Word deals with how to fix the formatting in a particular document. Often the formatting screw ups occur because someone was not properly using styles. Somethimes, however, the formatting is screwed up because the document is imported from aonther format or because someone pasted text without using the Paste Special function.
The best way to deal with this formatting problem is to take the formatting back to square one. You can easily do this simply by selecting the text and then pressing Ctrl + Enter. This converts the formatting for the selected text to the Normal style. Once it is there, you can then reformat the document as appropriate.
