Most tools have toolbars offering one-click access to frequently-used commands. For example, the Editor has a toolbar for operating on source code.

You may prefer to remove such toolbars. You can control whether a tool displays its toolbars by the option Show Toolbar .
To hide toolbars for a particular type of tool:
You can also customize the toolbar by removing rarely-used buttons, changing the image size, choosing whether an image or text label (or both) is displayed, and adding or removing separators between groups of buttons. To do this on Cocoa, raise the context menu on the toolbar, choose Customize Toolbar... and make your selections in the standard Mac OS X way. You can also use the toolbar's context menu directly to select whether this toolbar's buttons show an icon, or text, or both. To remove a toolbar button on Cocoa, simply select Remove from the context menu.
Note: The functionality of each toolbar is available elsewhere. For example the Editor's source code operations are also available on the Buffer , Definitions and Expression menus.
