I can’t find an option for this. Sometimes you don’t want to hyphenate text at the end of a line, as in titles or section headers, etc… How do you accomplish this in TeXmacs?
How to selectively disable hyphenation on line-breaks? Or how to disable justification?
I think it is \rigid.
But that may not be what you want, in that it does not break its contents. i think you want to break contents only at white spaces. Let us see if someone else knows.
I think a workaround is putting the text in a table cell.
Yes, that is what I want. Typically, titles are not justified and hyphenated. I.e. the right side should be ragged.
