Im having an issue with inconsistent vertical space
If I do latex export \\es at eol produce blank lines
However with html export they appear in output but not consistently
org version 8.2.5e
emacs version 24.3.1
Below a cut-down version from a file I see it happening
------------
#+TITLE: Equational Reasoning in Logic
#+AUTHOR: Rusi
#+OPTIONS: toc:nil
* Object and Meta language
Look at the following proof
#+ATTR_LATEX: :mode math :environment flalign
P \wedge (Q \vee P)\\
" \wedge distributes over \vee " \\
= (P \wedge Q) \vee (P \wedge Q) \\
" Idempotence of \vee " \\
= P \wedge Q \\
\\
\\
Observe that:
- Each proof step has an expression
- Each step also carries an implicit statement, that the given expression
is $True$ . So, in the first step, we have an implicit statement: P \wedge
(Q \vee P) = True

This case is easy: just delete the last two \\ and you are done. I take
it that your real case is more complicated.
Running org-element-parse-buffer on your buffer might be illuminating:
the "internal" \\ get parsed as
(line-break (:begin 267 :end 270 :post-blank 0 :parent #3))
but the last one (I used a buffer with just one trailing \\, not two)
gets parsed as
#("\\\\
" 0 3 (:parent #3))
i.e. a string, so it gets copied to the output. When the output is
latex:
,----
| " Idempotence of \(\vee\) " \\
| = P \(\wedge\) Q \\
| \\
| % Emacs 24.3.50.2 (Org mode 8.2.5g)
| \end{document}
`----
the \\ are processed by pdflatex and become empty lines. When the output
is html:
,----
| " Idempotence of ∨ " <br />
| = P ∧ Q <br />
| \\
| </p>
`----
they are processed by the browser which does nothing special with them,
so they are shown in the output.
Why exactly the last one is parsed as a literal string and not as a line
break, I don't know. Nicolas will probably explain all. The only thing I
can say is that if there is something other than whitespace on the line
before the \\, it gets parsed as a line break; if there is only
whitespace (or nothing), it gets parsed as a string. That's probably a
rough description and not quite right in all particulars, but I hope
it's close enough.

So the question remains: How to get generic, consistent vertical space?

You can try a verse environment. There is an implicit line break at the
end of each line, indentation and vertical space are preserved.

That's exactly that. I even added the following comment in
`org-element-line-break-successor':
;; A line break can only happen on a non-empty line.
I'm not sure why, though. It may have to do with the fact that there is
no easy way to escape backslashes in Org (AFAIK).
I think we can remove this rule if we first add a "bslash" (or some
other name) entity in `org-entities'.

I am normally working in LaTeX but want to try out org-mode for a book.
During the process I have to export Word Processing documents
(LibreOffice/MS Word) for other less privileged people who do not know
Linux/Emacs/LaTeX :)
My first problem is how to do this (\vspace{}) in orgmode (Know I how to
get the 'enumerate' environment working in orgmode):
\begin{enumerate}
\item Die eerste paragraaf van die formulier word die woorde
``verbondskinders'' gebruik en gepraat van ``God se beloftes in die
doop''.
\begin{enumerate}
\item Wat beteken die term ``verbond''?
\vspace*{1.5cm}
\item Wat het God jou belowe toe jy gedoop is?
\vspace*{1.5cm}
\end{enumerate}
It will be nice if I can embed such LaTeX snippets directly.
Regards
Johann

Why not use the enumitem package to add that space automatically?

Thanks Marcin. I did not know about enumitem. That might be useful in
LaTeX.
But my problem here is not LaTeX, but how to do it using orgmode and then
export
it to LaTeX and ODT
Also - enumitem might not be the final answer to my problem here because I
do
not always need the same space between items.
Regards
Johann

AFAIK, you can give Org arguments to environments. Also, you can use
enumitem to change the spacing between items per environment, not only
globally. And you can always use literal LaTeX, see (info "(org)
Quoting LaTeX code").
