Removing a button from a toolbar
In this section:
To remove a button from any of the toolbars in the main window of the IDE, click the Toolbar Options button and choose Add or Remove Buttons>Customize. Ignore the Customize dialog box that is opened.

Right-click on the toolbar button that you want to remove and choose Delete from the context menu.
Note
If you instead of removing a button want to hide it temporarily, see Showing/hiding toolbar buttons.
