Custom Commands

I don’t change any default command or environment, which means you can use all the basic LaTeX commands and environments as before. Besides, I define 4 commands

  1. \email: create the hyperlink to email address.
  2. \figref: same usage as \ref, but start with label text Figure n.
  3. \tabref: same usage as \ref, but start with label text Table n.
  4. \keywords: create the keywords in the abstract section.
