Thanks for the cheers.

Use "automatic" page type instead.

You do not want a command to move up or down one page. And actually, I
am not even sure TeXmacs has this.

Probably you want to use the "switch" structure and some tools to
easily convert to and from switches.

The idea would be this:

(tree->object (the-buffer)) => the buffer content as a scheme object

Build a list of (document ...) where each document is the content of
one slide.

set the buffer to:
`(document (hide_expand "switch" "" (tuple ,@list-of-document)))

move the position to inside the switch, a the path may be '(0 1 0)

(switch-select 1)

NOTE: switch-select is defined in edit-fold.scm and is private, so you
would have either to copy the definition in your code, or
(inherit-modules (texmacs edit edit-fold)).


Sorry for the complicated answer... I have a some experimental code
which does some complicated construction and browsing of switches, but
it depends on outdated function names and it is quite big.
