Do you mean you want to "lock" the Home Tab of the Ribbon so that the font
size list is always visible? I don't believe that can be done -- it would
prevent accessing needed commands & features on the other Tabs.
What you might consider doing is adding the Font Size List as well as any
other often needed controls to the Quick Access Toolbar. You can include
just about anything you want on the QAT: Click the Office Button then the
Word Options button, select Customize from the categories list on the left.
Use the Help if you need more information.
