I want to hide a very long LaTeX input text in one passage. If I use % for every line I need too much time to hide all the lines. Is there a command that can hide the text in one single passage?

Some editors have a shortcut for inserting a % in every line of a marked text part. Apart from specific packages you could just define a simple command that throws away its argument (doesn't use it for something), like the following:

\long\def\comment#1{}

You can then insert it at the beginning of your text passage and add the closing bracket at the end.

\comment{
   Text ...
}

  • Perfect! There are some possibilities that the latex input become gray also? Like when I use % ?

    Since this is an editor specific highlighting feature: no. At least not if you are using this solution. If you use the shortcut (Ctrl+T in TeXmaker & TeXstudio) then every line will be gray with a leading % sign. May 17, 2015 at 14:08
  • Teah! '' Ctrl+T '' is the solution. Thank you :*
