The HTML output of the dbslide.dsl stylesheet employs some rather simple JavaScript/JScript code to simplify the navigation during the presentation. The purpose of this is to allow even the most nervous speaker to move through his presentation gracefully. Unfortunately JavaScript is a browser compatibility issue, so not all of the following might work on the browser where you run your presentation.
Use the following keys to get around in your presentation:
Moves on to the next slide
Moves back to the previous slide
Goes back to the start page.

If nothing else helps, you can use the hyperlink-based navigation that the DocBook stylesheets generate by default. If you use the CSS stylesheet provided with the dbslide package, these links (prev and next in the upper left and upper right corner, respectively, just above the separating line) are still present, but invisible as they are rendered "white on white". This was done for aesthetic reasons and can be changed in the dbslide.css stylesheet. If you move the mouse cursor into the upper left or upper right corner, you will notice that the cursor changes shape right over the invisible links.
