I am sort of restating this question -- however only sort of.
I will (1) describe a problem, (2) assume something about the functions of ledpar, and (3) ask a question.
1. Problem
I am typesetting a bilingual edition of a text: edition on the left, translation on the right page. Since the translation is much longer than the original, the pagesynchronization is rarely correct (I assume that the unequal lengths of text on both pages is at least in part responsible; this assumption could be wrong, of course).
Anyway, I would like to be able to insert a pagebreak manually an thereby to synchronize the contents manually. AFAIK such a manual pagebreak is not implemented in ledpar. There is this fine solution, but I want to state the problem from a slightly different angle.
2. Assumption
I guess ledpar works like this:
- looking at the text on both sides,
- trying measure the contents on both sides,
- deciding for a portion of text on the left page,
- using some sort of command in order to let the left page break after that portion,
- trying to measure the corresponding text on the right page,
- trying to determine an equal portion on the right page and the correct spot for the break,
- using some sort of command in order to let the right page break,
- go to the next portion of text... etc.
3. Question
What is this command that lets the page break? This command -- or something like it -- must exist, because ledpar uses it itself automatically all the time, right? So, can I just manually use this very same command that lets the page break myself wherever I want? If this command is some bigger function, then I think it should be possible to define a command I could execute in my text.
