Hi Hannan,
I had been reading a bit your pdf file and i must say its very good and i learned from it a lot.
I must say that some of the things like \dfrac i hadn't succeed to apply in my LyX.
You can also have a look in the source file. I published it as LyX-file under
http://wiki.lyx.org/pmwiki.php/LyX/LyXMathebefehle#download
I was looking on your matrix section, trying to look for a way to create a matrix in the size I want without the need to to go to Math Panel. Do you know how to do it?
You can use the commands \matrix, \bmatrix etc. in a formula, to create a matrix box. Within the box use the menu Edit -> Math to add and delete colums and rows (shortcuts M-m c i, M-m c d and M-m w i, M-m w d).
The next version of my doc will contain this information.
I hadn't seen in your article the use in M - ( or { or [ for creating a pare of ( ) or {} or []. Maybe its because i don't know so much German...:). (M - stand for alt).
The shortcuts for paranthesis pairs are described in chap. 5.1.2 as "Alt-m Klammer", which means "M-m parenthesis" (e.g. "M-m {" ).
Hopefully I'll find some time to translate the document to english, so that everybody will be able to read it.
regards Uwe
