Another way to show materials step by step in your presentation is using the [[RawSteps]] module. However that approach is going to create a page for each step, so that your presentation document may end up clogged with too many pages. Nevertheless it has the advantage of being able to go backward through the steps, and the resulted PDF file may be viewed in any PDF viewer.
Here we give an example using the Stepper which is buit in ConTeXt. In order to use it one has to add the following lines at the beginning of the source file:
\startitem This is shown step \FlushStep \stopitem
\startitem This is shown step by\FlushStep \stopitem
\startitem This is shown step by step \FlushStep \stopitem
\stopitemize
\StopSteps
Notice that the resulting PDF file must be viewed in a PDF viewver such as Acrobat Reader (the stepping procedure doesn't ork in Apple's Preview.app, nor in TeXShop).
