Starting PowerPoint and opening presentations
When you first start up PowerPoint, you will be presented with a dialog
box:

Here you have a choice of either opening an existing presentation, or creating
a new presentation. To open an existing presentation, choose that option,
browse to the presentation you want to open, and double click on it.
Saving and closing presentations
To save a presentation, simply click on the disk icon on the top left of
the screen. Label your presentation descriptively.
