Displaying text on a page in several steps

Displaying text on a page in several steps

[Cecil Westerhof]

I want to have several points on a page, but have them displayed one
after the other.

For example, the complete page is:

MY POINTS
1. The first point
2. The second point
3. The third point
4. The fourth point

Initially you see:
MY POINTS
1. The first point

After giving space you see:
MY POINTS
1. The first point
2. The second point

When giving again space, you see:
MY POINTS
1. The first point
2. The second point
3. The third point

And another space gives:
MY POINTS
1. The first point
2. The second point
3. The third point
4. The fourth point

Is this possible?

Something went wrong and I posted the rest to Hans Hagen instead of to the list.

I have the attached tex-file which should be correct I think. But it
goes wrong: see the attached log-file. Anybody an idea what is
happening?

Dimensions can be in units of em, ex, in, pt, pc,
cm, mm, dd, cc, nd, nc, bp, or sp; but yours is a new one!
I'll assume that you meant to say pt, for printer's points.
To recover gracefully from this error, it's best to
delete the erroneous units; e.g., type `2' to delete
two letters. (See Chapter 27 of The TeXbook.)

That works. I can continue. ;-}

Why is this statement needed.?

Shall I change the wiki page, or is this only temporally needed?

Invalid setting in s-pre-61.tex

\setupinteractionmenu
  [bottom]
  [offset=overlay]

The offset key accepts only dimensions but not keywords like it did in mkii.

> Shall I change the wiki page, or is this only temporally needed?

To use the stepper only you don’t need this because it
comes from the file s-pre-60.mkiv (or “pre-stepwise”).

\usemodule[pre-stepwise]

\setupinteraction[state=start,click=off]

\setupbodyfont[palatino]

\starttext

\StartSteps

\starttabulate
\NC test \FlushStep \NC test \FlushStep \NC \NR
\NC test \FlushStep \NC test \FlushStep \NC \NR
\NC test \FlushStep \NC test \FlushStep \NC \NR
\stoptabulate

\StopSteps

\stoptext

The module pre-61 (or “pre-stepper”) is only the presentation style.
