Question

Once I have entered text into a presentation, how do I modify the font style of the text? Select the text and use options available on the Format Text tab. Fonts cannot be modified in the PowerPoint application. Select the text and use the format options available on the Home tab. Delete the text and retype it after you have selected the appropriate format.

Answer 1

Select the text and use options available on the Format Text.

The Microsoft Office package offers a variety of options and is a very powerful tool for text modification. Among these tools is also Powerpoint (if you're talking about PowerPoint). All of them in any case make available text modification and Text formatting. 

Answer 2

If you are using Microsoft Word(which i would recommend) then go to the top left corner of the screen and there should be a font section where you can select a font and right next to it is the sizing range for the size of your letters. It depends on the format or the way it fits into the screen. I have an Apple Mac at my house and i use Microsoft Word. I also use a Microsoft computer at my school in digital literacy class.
