I use Lyx on a Mac Intel laptop. While I find it very useful, there
are some difficulties with writing math.
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).
2. Selection by dragging in a math formula is very sensitive. It
often selects too little and when tries to correct it overshoots.
3. Cursor placement is very sensitive in math mode: If I put the
cursor between to symbols the selection point often appears outside
the range of the two symbols. When selecting by use of the shift key
and say a right arrow the selection often goes to the left!
I haven't seen this.
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...
5. The default is that equations are unnumbered. I would prefer that
the default be that all equations are automatically numbered. Is
there a way of setting this?
You can certainly do this through the GUI (Insert->Math->Numbered
Formula). Or via keyboard shortcuts you can do Ctrl->m and then Alt-m-
n. Alternatively, you could bind your own shortcut key to do this in
one shot.
Thanks
