For Seniors: How to Use the Mini Toolbar in Office 2010
In Office 2010, you can quickly change settings using the mini toolbar. The mini toolbar appears whenever you right-click text in Word, Excel, or PowerPoint.
The mini toolbar provides a quick-access version of the Font group on the Home tab, plus a few extra buttons from other groups. Hover your mouse over each button to find out what it does.
In Word and PowerPoint, the mini toolbar also is available when you select text; a faint, partly transparent version of the mini toolbar appears above the selected text. If you move the mouse over it, the mini toolbar becomes solid and usable.
If you find it annoying that the mini toolbar appears for selected text (some people do), choose File→Options and then deselect the Show Mini Toolbar on Selection check box.
