comment Capital Omega problem, I can not renewcommand it
I have found the reason! Here is my MWE, you can check if xeCJK package will conflict with that command line I gave before: \documentclass{article} \usepackage{amsmath,amssymb} \renewcommand{\Omega}{\varOmega} \usepackage{xeCJK} \begin{document} $\Omega$ \end{document}

comment Capital Omega problem, I can not renewcommand it
I do not want to change all the \Omega into \varOmega, for there are almost 50 files in sum, each one of which contains many \Omega.

comment Capital Omega problem, I can not renewcommand it
The following works fine for me too: \documentclass{article} \usepackage{amsmath} \usepackage{amsfonts} \usepackage{amssymb} \renewcommand{\Omega}{\varOmega} \begin{document} Here is a test for $\Omega$ \end{document} But when I insert the line \renewcommand{\Omega}{\varOmega} into my previous huge tex-file, it does not work fine anymore. It always give the information below: Command `\Omega' already defined. It is very strange!

comment How to configure Okular so that I can locate the line approximately correct, when in forwardPDF
No, I have not find a solution for locating and highlighting the relevant line in okular in forward search. And now I am using Texstudio, it works very well in Debian Wheezy, whose function of forward search and backward search is fairly wonderful.

Voila, your suggestion is very useful and helpful. With your source codes, I have accomplished my task immediately. Thank a lot.

comment not implies, not Leftarrow, description in the middle of an arrow in TikZ-cd
Dear percusse, how could I enlarge the distance of the two parallel lines of the implication sign "===>". I have tried modified your source file, but got none hints.

comment How to adjust the blank space between the top of the left curly brace and the contents?
I have tried your example with "\usepackage{scalerel} \usepackage{verbatimbox}", but there is something wrong. I can not get the desired result. I do not know how to install the scalerel style. I simply put the scalerel.sty in /home/programfiles/texlive/2012/texmf-dist/tex/latex/base/scalerel.sty, then run the command: > texhash. And then I compile the source file (just that you have modified), and then I got the wrong result. I put it then.

comment How to adjust the blank space between the top of the left curly brace and the contents?
I want to just decrease the VIRTICLE space between the upper tip of curly brace and the first equation of the system, Not The Horizontal Space.

comment How to adjust the blank space between the top of the left curly brace and the contents?
I want to let the first equation $x=x$ move up a little when using evironments of arrya, aligned, and cases, so that there is no more verticle space between the top of the curly brace and the first equation. Actually, the fourth method of using numcases is just what I want. But the drawback of this method is that it can not be allowed to use with other environments, such as gather, align, etc. And I am tired of adding \nonumber when I do not want the formulas be numbered.
