Fonts Limit the number of fonts to one or two. Keep font size large enough to be easily readable and use a very limited number of different font sizes. Modality Use non-modal windows whenever possible to give the user maximum control over the interface. However, modal windows may be used when it is necessary to focus the user's attention. Menus Drop-down menus provide the primary interface for many applications.
Users expect a certain degree of consistency in how different application's menus behave.
General conventions applying to menus are listed in the table below. A menu title is the word or phrase that appears on the menu bar when the menu bar is not in its dropped state. Menu titles should be a single word if at all possible. If a menu title does not have a corresponding drop-down menu, the menu title should end with an exclamation point. But this situation should be avoided if possible.
