You can quickly make blocks of text all capitals, or change blocks of capitalized text to lowercase.
Select the text you want to change (by selecting a text box or dragging to select specific words), or click in a text box where you want to type new text.
Choose Format > Font > Capitalization, and then choose one of the following items from the submenu:
All Caps: Changes all the text to capital letters.
Small Caps: Changes text to smaller capitals with larger capitals for uppercase letters.
None: Leaves text as you entered it and applies no automatic capitalization.
