1. Suppose I have a math symbol #1 which has is subscriptedt. I
now want to insert a second symbol #2 immediately to the left of
#1. When I try to put a subscript on #2 the insertion point
appears as a subscript on #1. This problem does not happen every
time but does most times.
When editing in math mode you will notice small boxes around your
text. These are analogous to {} in LaTeX. If you are adding a
term (#2 in your example) to the left of an existing subscripted
term, you must be sure that you are not within the box containing
the existing term (#1 in your example).
Unfortunately this does not cure my problem. If I am in a displayed
equation on the Mac version of Lyx, there are no small boxes around
individual symbols. There is only a single possibility for placing
the insertion point between two symbols them. That placement does
not distinguish which symbol it is closest to. The result is it
seems to consider the two symbols (#1 and #2) to be a single symbol
and puts the subscript behind #2 --most of the time.
What version of LyX? I am running 1.6 on an Intel Mac. There are not
boxes in this version, but little brackets under the term that
indicate the equivalent of {}. Again, if you have something like
a^2
then be sure that when you add
b^4 a^2
that the "b" term is not within the little "box" or brackets
associated with a^2.
4. The page position jumps around a lot. Partly as a result of an
equation compiling on the fly or un-compiling for editing an
equation. Is there away to turn off on the fly compiling and
select when desired? The default is that it seems to compile when
the equation typing is finished.
I think that you can turn off "instant preview" in the document
settings. I haven't done this, but it might do the trick for you
if you don't want to see this. However, it may not allow you to
see the compiled equation at all if you do that...
I have looked for this possibility and have not yet found it.
