Eliminate double spaces in documents other write

When working with text that others have created, use your software program's Replace feature to eliminate two spaces following periods (or other punctuation.)

Many people first learned to type on a typewriter, and were taught to press the space bar twice after a period. This was necessary then, but creates serious problems now.
Two spaces in a row each expand when the text is justified (i.e., set in lines of equal length), creating large, distracting spaces between sentences.

Simply select Edit>Replace and instruct your software to Find every instance of two spaces and Replace them with one space.
