On the Macintosh: Tab Key
In addition to its traditional function—moving the insertion point to the next Tab stop in a word processor, or advancing to the next cell on a spreadsheet—the Tab key has several special functions on the Macintosh, just as it does in Windows:
In the Finder, press Tab to select the next icon (alphabetically by name) in the current window. Press Shift-Tab to select the previous icon.
In dialog boxes (such as Open or Save dialog boxes) or windows with multiple panes, press Tab to move the insertion point from one area to another. For instance, in the Save dialog box, press Tab to switch between the list of files and the text field where you type a name for the file. Similarly, in the Get Info dialog box (select an icon and then choose File → Get Info), press Tab to alternately highlight item’s icon and the Comments field.
In Mac OS 8.5 and later, press Command-Tab to switch between open applications.

In Mac OS 8.5 and later, the application menu’s name and icon change to identify the current open program. (In previous OS versions, only the icon, not the name, of the active program appeared.)
