Section 1.6. Dock Taskbar

1.6. Dock = Taskbar

At the bottom of almost every Mac OS X screen sits a tiny row of photorealistic icons. This is the Dock, a close parallel to the Windows taskbar. (As in Windows , it may be hidden or placed on the left or right edge of the screen insteadbut those are options primarily preferred by power users and eccentrics.)

The Dock displays the icons of all your open windows and programs, which are denoted by small black triangles beneath their icons. Clicking these icons opens the corresponding files, folders, disks, documents, and programs. If you click and hold (or right-click, or Control-click) an open program's icon, you'll see a pop-up list of the open windows in that program, along with Quit and a few other commands.

When you close a program, its icon disappears from the Dock (unless you've secured it there for easy access, as described on Section 3.2.1).

Tip: You can cycle through the various open programs on your Mac by holding down the key and pressing Tab repeatedly. (Sound familiar? It's just like Alt-Tabbing in Windows.) And each time you just tap -Tab, you bounce back and forth between the two programs you've used most recently.

What you may find confusing at first, though, is that the Dock also performs one function of the Windows Start menu: It provides a "short list" of programs and files that you use often, for easy access. To add a new icon to the Dock, just drag it there (put programs to the left of the divider line; everything else goes on the right). To remove an icon from the Dock, just drag the icon away from the Dock. As long as that item isn't actually open at the moment, it disappears from the Dock with a little animated puff of smoke when you release the mouse button.

The bottom line: On the Mac, a single interface elementthe Dockexhibits characteristics of both the Start menu (it lists frequently used programs) and the taskbar (it lists currently open programs and files).

If you're still confused , Chapter 3 should help clear things up.
