    Note
    There are two things about the Dock that you can’t change: the
     Finder is always on the left end of the Dock, and the Trash is always
     on the right end. You can’t move them, and you can’t put anything on
     the far sides of them. Think of the Finder and the Trash as two
     bookends that expand to accommodate all the items in between.
    Dock Exposé
    Ever wanted to see all the windows an app currently has
     open? You can accomplish that easily with Dock Exposé. The way you
     pull this off is really slick: pick any running application, click and
     hold its icon in the Dock, and then select Show All Windows in the
     pop-up menu that appears. You then see something like Figure 3-18 . Any minimized
     windows show up as small versions below a subtle dividing line. Click
     any window to bring it to the front.

     Exposé
    The pop-up menu that appears when you click and hold an
     application’s Dock icon also lets you quit or hide the selected
     application. The menu also includes an Options submenu to let you keep
     the application in the Dock, set it to open each time you log into
     your computer, or show it in the Finder.
    Dock menus
    Every item in the Dock has a Dock menu. To access this
     menu, right-click or Control-click the item’s icon. What shows up in
     the menu depends on what you click and, in the case of an application,
     whether it’s running and what it’s doing. Application Dock menus
     typically include relevant commands. For example, if you’re currently
     playing a song, iTunes’s Dock menu lets you mute your computer, skip
     and rate songs, and so forth. All applications’ Dock menus include
     these options:
    Options → Keep in Dock or
     Remove from Dock, depending on current setting
Options → Open at Login (saves
     you a trip to the Users & Groups preference pane)
Options → Show in Finder
     (reveals where the application resides on your Mac)
Hide (hides all the application’s windows; equivalent to
     pressing ⌘-H)
Quit (closes the application; you’ll be warned if there are
     any unsaved changes; equivalent to ⌘-Q)
    The Dock menus for stacks (such as the Documents or Downloads
     stack) offer a different set of choices:
    Sort by options (Name, Date Added, Date Modified, Date
     Created, Kind)
Display as (Folder or Stack)
View content as (Fan, Grid, List, Automatic)
Options (“Remove from Dock” or “Show in Finder”)
Open [stack name]
    Stack view options
    That folder or jumble of icons (depending on how your
     preferences are set—jumbled icons is the default) on the right side of
     your Dock is called a stack . You can choose which view to
     use for each stack by opening its Dock menu (the previous section
     explains how). Here are your options:
    Fan View
This is the default view for stacks. If you click a stack
     that’s set to this view, it’ll fan out, making it easy to choose
     the item you’re looking for, as shown in Figure 3-19 . Fan View is nice when there
     aren’t a lot of items in a stack; it’s less helpful when there
     are more than a dozen or so items. If you use the arrow keys to
     select items in the stack, a blue highlight appears behind the
     current item; hit Return to open it.

Grid View
In Grid View ( Figure 3-20 ), you get to browse by icon,
     and you can use the arrow keys to highlight an item. If that
     item is an application or a document, hitting the Return key
     starts the application or opens the document. If the selected
     item is a folder, hitting Return opens another Grid View window that displays the
     folder’s contents.

List View
List View ( Figure 3-21 ) displays the
     stack’s items as a list on the same background used by Grid
     View. List View is a bit pedestrian compared list Fan View or
     Grid View, but that doesn’t mean it’s useless. You can scroll
