Use title-style capitalization for the title of each menu item within a pull-down buttons menu. If you need to provide a list of mutually exclusive choices that arent commands, use a pop-up button instead.

Action buttons are often used in toolbars, but can also be used in the content area of a view beneath a table view. Users are familiar with the meaning of the standard gear icon. Ideally, an action button should contain fewer than twelve commands. For example, the default toolbar in Finder includes an action button that can initiate operations related to the currently selected item. ![]() An action button used in this context should adopt the gradient button style. Other than when displayed beneath a table, an action button shouldnt appear within the content area of a window.
