Michael, well, a \linebreak (*) is not what people want to express by "\\". See my enclosed example. I hope it goes through the list, we'll see. To my mind you should rethink your advice. People should use real paragraphs. This is what I would suggest in such situations most of the time. I'm aware this is sometimes difficult or impossible (think of the need for using \long\def for example), but we're really in a TeX discussion here. It's not that I want to quit this discussion as I think we can all learn from each other. I totally agree, that "\\" is often use wrongly. It harms the paragraph breaking algorithm of TeX and I constantly suggest to use paragraphs instead. While you then may need to fiddle with \parskip and \parindent, it is the only true solution to generate lines in LaTeX (to my knowledge). But in the end of the day if we want to give (and publish) a founded advice, we should probably ask a TeX guru (which I'm not). Best, André (*) at least when not in a raggedleft, raggedright or center-like mode, which happen to add some left and right horizontal material to each line at the beginning and end to suppress the inter-word glue blowup Am 08.10.2012 um 09:36 schrieb Michael J Gruber: > Hi there, > > I don't care personally, but '\linebreak' is the correct way to enforce > a linebreak in TeX.

Sorry for coming back to this email after such a long time of silence. While I totally agree with you in that "\\" to be considered harmful. However, I'm rather unsure whether \linebreak is the proper solution. I always suggest to use real paragraphs to generate breaks, as it creates separate vertical material in TeX. While I do understand your intention, I'm not sure whether we should document your solution. As it's a TeX problem, we may better not comment on that at all rather than proposing a wrong solution. >> >> Best, >> >> >> André >> >> >> Am 22.07.2011 um 14:26 schrieb Michael J Gruber: >> >>> The widespread use of \newline (in the incarnation \\) for enforcing >>> linebreaks causes many problems with the alignment of parboxes. >>> \linebreak is the correct way to force a line break without destroying >>> alignment. >>> --- >>> examples/text/halign.txt | 4 ++++ >>> 1 files changed, 4 insertions(+), 0 deletions(-) >>> >>> diff --git a/examples/text/halign.txt b/examples/text/halign.txt >>> index a9d15e3..b1453d0 100644 >>> --- a/examples/text/halign.txt >>> +++ b/examples/text/halign.txt >>> @@ -23,3 +23,7 @@ well, when you do not create a parbox. >>> !!
