Dear Wolfgang,

I read your detailed explanation about the difference between "overlay" and "layer".

Here is your sample code using layer.

\starttext

\definelayer[test]

\setlayer[test][x=3cm,y=6cm]{ONE} \setlayer[test][x=8cm,y=2cm]{TWO} \setlayer[test][x=2cm,y=9cm]{THREE}

\flushlayer[test]

\stoptext

It shows ONE, TWO, and THREE in the same page.

I'd like to show each word one by one when I click, so I tested the following code.

\setupinteraction[state=start] \usemodule[pre-60] \starttext \definelayer[test1] \definelayer[test2] \definelayer[test3] \setlayer[test1][x=3cm,y=6cm]{ONE} \setlayer[test2][x=8cm,y=2cm]{TWO} \setlayer[test3][x=2cm,y=9cm]{THREE} \StartSteps \flushlayer[test1] \FlushStep \flushlayer[test2] \FlushStep \flushlayer[test3] \FlushStep \StopSteps \stoptext

This code produces 3 page output one word per each page. There is no need to click the mouse. I may misunderstand about the layer.

However, is there a way to show each word one by one in the same page when I click.

\setupinteraction[state=start] \usemodule[pre-60] \definelayer[test] \starttext \StartSteps \setlayer[test][x=3cm,y=6cm]{ONE}\FlushStep \setlayer[test][x=8cm,y=2cm]{TWO}\FlushStep \setlayer[test][x=2cm,y=9cm]{THREE}\FlushStep \StopSteps \flushlayer[test] \stoptext Wolfgang
