The toolbar at the top of a window contains controls relevant to the functionality of that window. So:

• The toolbar at the top of a script window contains controls for running and debugging your script.

• The toolbar at the top of a dictionary window contains controls for switching between dictionary view and explorer view, for reloading the selected entry, for activating or quitting the target application, and so on.

• The toolbar at the top of the Apple Event Log window contains controls for determining what is logged and in what format, and can contain controls for running the corresponding script.

In general, the functionality in a toolbar is available also from menus, so feel free to hide the toolbar if you want to conserve screen space. However, some toolbar controls are not available elsewhere. For example, the Search field in the dictionary window toolbar has no exact parallel elsewhere in the interface.

To show or hide a toolbar:

• Choose View > Show Toolbar or View > Hide Toolbar (it’s the same menu item). Alternatively, click the “lozenge” (oblong) button at the right end of the title bar.

To customize a toolbar:

• Choose View > Customize Toolbar. This brings up the Customize Toolbar dialog, where you can determine what controls appear in the toolbar, as well as setting the icon style and size. Alternatively, control-click in the toolbar icon area to bring up the contextual menu that lets you do the same things. Even without the Customize Toolbar dialog, you can Command-drag an icon in a toolbar to change its position or remove it from the toolbar. Your changes apply (immediately) to the toolbars of all windows of the same type. Thus, customizing the toolbar of a script window customizes the toolbars of all script windows, and customizing the toolbar of a dictionary window customizes the toolbars of all dictionary windows.
