Well 'how things work' in TeXmacs is a vast topic...

'Where they are much explained', on the other hand is an easy
question: nowhere. That mean you have to make make experiments and
sometimes read the source.

Joris seems busy, but since numbered lines is a common requirement I
made a package to this effect. In attachement.

I could not figure a way to have the line numbers and the line text
vertically centered, but I think that is already not too bad.

  Define a numbered-lines macro.

  name: name of the macro to define.

  compute: function producing a line number

  display: macro displaying the decorated line, its argument is the line
  number, it must apply the function 'theline' to compute the line number.

  margin: macro setting the surrounding environment
