User Input

Keyboard Focus and Navigation

In default keyboard access mode,focus moves only between fields that receive keyboard input. Mac OS X also provides the option of full keyboard access mode, in which users can navigate through windows and dialogs. This section discusses the default keyboard access mode. For information on the full keyboard access mode, see Accessibility Overview.

When using the mouse is undesirable, difficult, or impossible, users can use the keyboard to move the onscreen focus (highlight) to text entry fields, list boxes that support type-ahead, scrolling lists, column views, and list views. In Roman systems, focus always begins at the first field that accepts keyboard input and follows a reading path from upper left to bottom right.

Focus is indicated with a ring in the appearance color (Aqua or Graphite) as shown in Figure 8-1 and Figure 8-2

In list and column views, selected items should be highlighted to the full column width or row height. In column view, the selected item has a dark highlight and the parent item has a lighter highlight. When a window becomes inactive, all selections inside it should become the lighter highlight color.
