I am making some slides using the Swoosh style in simpleslides module.
I wanted to reveal some content sequentially.
I occasionally use the following macros for quick and dirty stepwise effects. This is for really simple material (no counters, no glues ...)

Hi,
this is awesome, but could you please explain why it works? I don't understand what is defined by \def\StartSteps#1#2\StopSteps and also why are \gobble and \oneofone used in such a way when they are single-argument commands.
