Hi Tommaso,
Thanks for your mail, and for the time you spent writing it!
LyX is really a good tool for me, especially because I have
horrible/unorganized writing.
So, I actually work-out all the math directly with LyX.
What I liked about your video was that I could "find and replace" math.
Sometimes/many times, I change my mind and decide to call a parameter with a
different name.
But LyX 1.6 doesn't seem to be able (yet) to do it.
I have no problems with actual text, just the math.
Is it true, like others on the forum had said, that this feature will be
incorporated into LyX 2 ver? I hope so.
This is the main reason why I need to export, then find and replace.
So, thanks for your mail,
Regards, Erez
