The toolbar at the top of the Mac OS X Snow Leopard screen gives you one-click access to many basic tasks. You can customize the icons that appear on Mac’s toolbar to facilitate your work style and preferences. The default icons on the toolbar include:
Back and Forward: The Back button moves you to the previous window’s contents. If you use the Back button, the Forward button appears.
View: Click this control to toggle between the four view modes (icon, list, column, or flow).
Quick Look: Click this control to display a window with the contents of the selected file or document without launching the corresponding application.
Selecting a folder and pressing the spacebar displays a summary of its size and last modification date.
Action: Click this pop-up menu to display context-sensitive commands for the selected items.
Search: You can search for a file or folder using this box.
Adding or deleting items from the toolbar is a great way to customize Mac OS X. From the active Finder window menu, choose View→Customize Toolbar. You see the sheet shown here.

You can also hold down Command and drag any item off the toolbar, or hold down Command and drag toolbar items to reorder them.
You can always drag a file or folder into the Sidebar column at the left of the Finder window.
To remove an item from the toolbar, drag it off to the center of the window.
Naturally, you can swap item positions. Just click an item, drag it to its new spot, and then release the mouse button.
To choose the default toolbar configuration or to start over, drag the default bar at the bottom of the window to the toolbar at the top.
This is the toolbar equivalent of tapping your ruby slippers together three times and repeating, “There’s no place like home.”
To toggle between displaying the icons with accompanying text (the default), the icon only, or a text button only, click the Show pop-up menu at the bottom of the Customize Toolbar dialog.
After you arrange your toolbar as you like, click the Done button.
