Let’s say your memorandum cites 28 U.S.C. § 1331. Let’s say the citation occurs near the end of a line, so that the § is at the end of one line and the 1331 is at the beginning of the next. How do you keep the two together on the same line with a space in between?
Answer: You type a non-breaking space, also known as a hard space or a fixed space. A non-breaking space prevents an automatic line break at its location.
Web-page coders create a non-breaking space by typing the HTML code “ ”. That doesn’t help you if you’re writing your memorandum in Word. But this tip will: To type a non-breaking space, just hold the CTRL and SHIFT keys down while pressing the space bar once.
A similar trick works for typing a non-breaking hyphen: hold the CTRL and SHIFT keys down while pressing the hyphen key.
