I am making some slides using the Swoosh style in simpleslides module.
I wanted to reveal some content sequentially.

simpleslides does not support stepwise presentation of material.

I occasionally use the following macros for quick and dirty stepwise effects. This is for really simple material (no counters, no glues ...)

\usemodule[simpleslides][style=Swoosh]
\def\StartSteps#1#2\StopSteps%
  {\dorecurse{#1}{\long\setvalue{\recurselevel}{\gobble}}
   \dorecurse{#1}{\long\setvalue{\recurselevel}{\oneofone} #2}}

\long\def\gobble#1{}
\long\def\oneofone#1{#1}

\starttext
\StartSteps{3}

\SlideTitle{Context can be used for \dots}

\null

\startitemize[n]

 \3{ \item Making slides for presentations }
\stopitemize

\StopSteps

\stoptext

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.

Regards,
