Word Only and Word Wrap

Word Only replaces only words, so for example, you are looking for the word "turn" and you want to replace it with some other word, like "walk", when the search comes across the word "return", it would not replace the letters t-u-r-n in the word "return", thus preventing it from becoming "rewalk". It would only replace the word "turn" with "walk" in any case.

Word Wrap prevents your sentences from continuing to the right indefinitely as you type, once the letters touch the right edge of the text box, they return to the beginning of the left side of the text box.
