Macworld Forum visitor, Glenn Blaylock, lost his way in Word X while customizing menus. In this process he accidentally pulled the Format menu off the Customize toolbar and when he did, Format disappeared from Word's menubar. "Now," he writes, "I can't figure out how to put it back."
Glenn, you might try this:
Select Customize from Word's Tools menu and in the resulting Customize window, click the Toolbars tab. Select Menu Bar from the list of toolbars. Now click the Commands tab and scroll the Categories list to the bottom, where you'll spy Built-in Menus. In the Commands field to the right, select the Format entry and drag it to the Menu Bar toolbar. Click OK to dismiss the Customize window and the Format menu will be back in all its former glory.
