How to Hide or Show Snow Leopard's Status Bar and Toolbar
That strip of icons across the top of Snow Leopard’s Finder window is called the toolbar. Mac OS X Snow Leopard lets you show it or hide it — if you want more screen space. The status bar is another feature you can choose whether to display.
You can toggle the display of the toolbar in an active Finder window in one of three ways:
By clicking the toolbar button located in the upper-right corner of the Finder window
By pressing Command+Option+T
By choosing View from the Finder menu and then choosing Hide (or Show) Toolbar
Hiding the toolbar also hides the Sidebar, which many Mac owners dislike.
The status bar at the bottom of the Finder window displays a number of helpful informational-type tidbits about the window’s contents. Depending on what you’ve opened, the status bar can include
Statistics: See the number of items in the window and the amount of free space remaining on the volume.
A write-protect icon: This icon looks like a pencil with a line running through it. This indicates that you don’t have write permissions for the contents of the window — or the volume where the contents reside. (Note that this doesn’t necessarily mean that folders at a lower level are write-protected as well.) You’ll typically see this icon when you’re viewing the contents of a CD or DVD, where everything is write-protected.
The current automatic icon view setting: For windows in icon view, the status bar can display either a grid icon (indicating that the icons are set to snap-to-grid) or four tiny icons (indicating that the icons are displayed in a sorted order).Check the status bar to scope out your write permissions.
To toggle the display of the status bar, choose View from the Finder menu and then choose Show/Hide Status Bar.
