Sorry, I cannot help but ask for the functionalities that came with Beamer. But these are the essential ones.
The ConTeXt stepping mechanism uses javascript and works only on Adobe Acrobat. For that reason, jI use some homegrown macros for stepping through my slides. These are not as feature rich as beamer macros, but get the work done.
I had not designed them for stepping through math, but they can be used for that purpose. For example, the following file:
\environment steps.tex
\setuppapersize[S5]
\starttext
\StartStepping 4
\startformula
\frac{ \ONLY 1 \phantom {-b \ONLY 2 \phantom {{}\pm \sqrt{b^2 - 4ac}} }}
{ 2a }
\stopformula
\StopStepping
\stoptext
gives the attached pdf file. If you want to use them to step through math,
then it may be better to create a wrapper around \ONLY n \phantom to save
some typing.
These were meant for private consumption, so they are not documented. But you can look at some examples of the resultant output at my website: http://www.ece.mcgill.ca/~amahaj1/talks.html
