In a package file:

<assign|list-save-state|\
<macro|label|\
<quasi|\
<assign|<unquote|<arg|label>>|\
<value|item-nr>\
>>>>
<assign|list-restore-state|\
<macro|label|\
<assign|item-nr|\
<value|<arg|label>>\
>>>

In a document using the package:

<\enumrate-numeric>
<item>This is the text of the first item.

<item>This is the text of the second item.

<item>This is the text of the third item.<list-save-state|potato>
</enumerate-numeric>

Some unstructured remarks.

<\enumerate-numeric><list-restore-state|potato>
<item>This is the text of the fourth item.

<item>This is the text of the fifth item.
</enumerate-numeric>

Here I have used the label "potato" to save and restore the state. A
potential problem is that some other package or even texmacs itself
could be using the word "potato" to name some some environment variable.
To minimize the risk of name collisions, the macros could have

<merge|list-saved-state-|<arg|label>>

instead of just <arg|label>, whereever that occurs. That would make the
label be "list-saved-state-potato" internally.

What still remains a disadvantage with all this is that unless one
switches to source view, the macro calls are hidden, and there is
nothing in the user interface that interacts with the macros. If you
forget the label you used, or forget that you put in the
list-restore-state, and later return to the document, you will be
mystified.

I just tried. It worked. Here is the contents of
.TeXmacs/packages/save-state.ts:

<TeXmacs|1.0.6.15>

<style|source>

<\body>

<assign|list-save-state|<macro|mylabel|<quasi|<assign|<unquote|<merge|list-saved-|<arg|mylabel>>>|>>>>


<assign|list-restore-state|<macro|mylabel|<assign|item-nr|<value|<merge|list-saved-|<arg|mylabel>>>>>>
</body>

To use it, in the second list environment, I inserted the environment
using the gui interface, then I pressed left arrow and checked that the
status bar said "before item", then I hit \, typed list-restore-state,
Enter, potato, enter.

Regards
Enrique
