(2) Creating multi-line equations breaks the equation in a brain-dead
place
Position the cursor in a single-line equation. Press CMD-return
Expected behaviour: create a new line, with all material before the
cursor on the present line to remain on the current line, and all
material after the cursor to move to the newly created line.
Actual behaviour: all material including and after the equals sign is
moved to the new line, irrespective of where the cursor was.
This is because cmd-return creates an eqnarray or an align environment,
depending upon whether AMSMath is in use, and the equals sign is used
for alignment.
This causes a lot of frustration to me, because often I only decide
that an equation has to be multi-line when I'm already half-way
through typing it. When this happens, I have to type CMD-return, then
CMD-z to undo the creation of the new line, re-position the cursor,
and type CMD-return again :-(
I agree that this isn't the most useful behavior...for me, but obviously
someone did choose this. Andre---do you have a view?
Much of the necessary code should already be there, because CMD-return
DOES respect the position of the cursor if the display equation is
already multi-line.
Yes, even I could change this...and I don't understand the math code at all.
This looks like Bug 2552, except that that bug claims `the parts...
are distributed to the slots depending on the cursor position', which
is not the case for me.
I've closed that bug. I think it's out of date now.
(3) confusing behaviour of space-bar in Math Mode
When typing a LaTeX command in Math mode, the space bar completes the
command and displays the symbol. This accords roughly with what would
be expected if one were typing LaTeX. What is strange to me is that
hitting the space bar in other circumstances causes the cursor to jump
to just after the math box, even if it were previously only half way
through. It's confusing to have such radically different behaviour in
very similar circumstances, and I can't think why the second behaviour
would be very very useful.
1.3 was actually superior, as the space bar was ignored in math mode
unless the cursor was positioned at the end of the math box. Extra
white space is benign in LaTeX, and I think this should also be the
case in LyX (as it is in text mode).
This seems like a bug. I agree: If you're at the end, you should exit;
if you're not, it should do nothing. But it's clear why it behaves this
way: It's an easy way to exit the formula...or, more generally, an inset
within a formula. You get the same behavior in superscripts, for
example. This is also an easy fix. I've got it working locally already.
