# 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.
