Hi Paul, Paul, I am using windows xp When you are on slide 1, press page down to go to next slide and so on. You can navigate through the presentation presing the page up and page down buttons. Also if you are in the middle of the presentation and want to go to the first slide press the home key. If you want to go to the last slide, press the end key. Hope this helps Petrina -- I am using the free version of SPAMfighter for private users. It has removed 263 spam emails to date. Paying users do not have this message in their emails.
