At the top of the main Z-Write window is a handy row of buttons for frequently used options. This is a standard Mac OS X-style Toolbar, with larger icons and text labels underneath. Via the Toolbar menu on the Edit menu, or via a contextual menu (Control-click) on the Toolbar itself, you can set the Toolbar to display in one of three modes: Icon and Text label, Icons only, or Text labels only.
If you prefer not to have the Toolbar, you can hide it by pressing Command-Y (or choosing "Hide Toolbar" from the Toolbar submenu). You can bring it back by using the same command again ("Show Toolbar"). Z-Write will remember the state (on/off, Toolbar mode) for each document, so you can have the Toolbar displayed for some documents and not for others.
If you prefer to not have the Toolbar for new documents or always want the Toolbar in a certain mode, simply set it the way you like it in your Default Template document and all new documents will be created that way.
Note: Below the Section List are several buttons for manipulating Sections. These buttons are displayed even when the Toolbar at the top is turned off. See "Working with Sections" for more information.
Briefly, here is what each button on the Toolbar does.
