1.9. Text Changes
When you place your cursor on text in the large window on your current slide, the Home toolbar will activate the areas that permit changes to the font and paragraph area.
These features work the same way they do in Word®. Select the text you wish to modify and then choose the new font, colour or spacing option from the toolbar.
Remember you are intending this presentation to be viewed on a screen perhaps in a large room. Font sizes should be no smaller than 24 point and ideally larger.
