Office2 lets you change the font face and size of text within your document.
To change the font face and size, first select the text whose font you wish to change and then select Font style from the character formatting menu.
A font face and size selector window will then appear at the bottom of the screen, letting you change the font of the selected text.
The font face and size of the selected text will be represented by the two wheels in the font selector window. You can rotate either wheel segment to change either the font face or font size of the selected text. The changes will be made when you press the Done button at the top right of the screen.
