Ok, I found the issue. My xml setups were introducing spurios whitespace here.

Both \penalty-10000 and \break seem to do the job.

Is there a difference between the two? Which one should I add to the wiki?

Best,

Denis

Probably not… It does give me linebreak, but I’m also loosing justification in the relevant line… So how should I go about it?

Best,

Denis

Probably this: \penalty-10000

Or is there a better command?

I just wanted check how I can indicate good places for linebreaks.

This pages should help me: https://wiki.contextgarden.net/Text_blocks/Typography/Delimiters_and_breaks

But the relevant paragraph just says: “If you would like to tell ConTeXt that this might be a good place for a line break, you can use” (Text stops here…)

What should I add there?`

Best,
