How to Get up to speed with PowerPoint 2007
Microsoft Office PowerPoint 2007 has a new design. The new Ribbon keeps the commands that you use most often visible while you're working instead of hiding under menus or toolbars that you have to hunt for. Also, commands that you may not have known about before are now very easy to discover. When it comes to designing your slides, live preview of style galleries lets you see how things such as backgrounds and shape formatting will look before you apply them. A new SmartArt graphics feature offers new diagram types and more layout options, and lets you convert text such as a bulleted list into a diagram.
So if you haven't used the new version of PowerPoint 2007, check out this tutorial and get up to speed.
