Switching to the Mac: The Missing Manual, Mountain Lion Edition

Dock = Taskbar

At the bottom of almost every 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 the right edge of the screen instead—options that appeal primarily to power users and eccentrics.)

The Dock displays the icons of all your open windows and programs, which are denoted by small, glowing dots beneath their icons. Clicking these icons opens the corresponding files, folders, disks, documents, and programs. If you click and hold (or right-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 Secret Menus).

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 if 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 it away. ...
