I've never used the breqn package, but with ordinary and AMS math environments,
hitting Ctrl-Enter in the middle of a long formula will break it (inserting a
line break, \\, in the LaTeX output). If that doesn't achieve what you want,
perhaps you could post a minimal example and a specification of what the output
should look like.
Paul
Thanks, Paul. I’m on a Mac so of course Control-Enter has no meaning. Usually this
translates to Mac-speak as Command-Enter. When I do Command-Enter in my equation,
which is unfortunately inside a align environment, it instead adds a row to the
matrix that represents the align environment. Ditto for Shift-Command-Enter. These
two commands in LyX are mapped as Insert -> Formatting -> Ragged Line Break and
Justified Line Break, respectively but invoking the menu commands with the cursor in
my equation has exactly the same effect: adding a row to the align matrix (above the
row where the cursor is.) When (Shift-)Command-Enter is done to a non-align display
equation a similar thing happens except now the non-align equation is converted to an
align equation with a blank new row _below_ the original equation.
Right now I guess I would be pretty happy with merely a way to make
Command-shift (Control-shift) do what is expected which is apparently break the
equation instead of creating a new row.
Jerry
Jerry,
I just created an align environment with two equations, the left side of the
first being ridiculously long. When I put the cursor somewhere toward the
middle of the left side of the long equation and inserted a break (using
Ctrl-Enter -- I'll get to the Mac part in a minute), it broke the equation and
inserted a new row. So
(x+x+x+x+...+x) =1
y =2
(where the right column contained the equal signs and integers) became
(x+x+x+...
+x+x+x+x) =1
y =2
where the right column is empty in the first row. See the attached minimal
example. Is this not what you want?
Regarding the key mapping, if you can find an unused key combo that you have a chance of

Paul,
I’ve attached an example showing a few things, mainly that
Command-(Control-)-Enter works with your equation and the equation from Section
18 of the Math manual but not with my equation.
Jerry
Jerry,
As explained in my reply to your prior message, the breaking in the
wrong place issue is apparently caused by the use of balanced [] around
the chubby part of the formula.
Regarding the rest, I also get a bunch of (apparently harmless) LaTeX
errors/warnings when I compile it. As to why the version you liked
failed to be transferable to its intended destination, I have no idea
about that. Although I have the breqn package installed, I have never
used it, so I don't know with what other packages (or standard LaTeX
things) it might be incompatible. The change I made in the previous file
also works here, and (since it is vanilla LaTeX and does not use the
dmath environment) should be portable.

Paul:
Thanks. The effect appears to work by adding another row to the matrix and
filling it with the partial equation. In your example the new row is on top. If
the long equation is moved to the RHS the new row is below.
I tried adding horizontal space to the second line of your broken equation but
Latex seems to ignore it: when I click outside the math box and the equation is
rendered, it is rendered without the horizontal space even though it was
visible while in math editing mode.
About Mac key mappings: According to the status line in the document window,
when I hit Command-Shift, it displays “(newline-insert newline;) and then icons
for “Command” and “new line” which is an arrow thingy. So I’m going to assume
that the key mapping is correct but that there is another problem, meaning…
…See my attached example. Attempting to break the line before the second
exponential (1) doesn’t break the line, (2) adds a matrix row above, and (3)
steals the = from the now-third row and puts it on the second row.
The failure to break with Command-Enter does not seem to be a function of the
align environment since it also fails in

OK, and thank you Stephan. To be clearer about #4 below. A file does not need to be re-opened to populate the list I require. For the list has already been populated by the most recent files that were opened. And those — the most recently opened — are the files I require.
