this is awesome, sticky please

I just learned a cool tip! You can make shortcuts for longer commands that you use often (for those of you writing longish reports, not equations online)

So if you wanted to replace \mathbb{N} with \N you could do:

\newcommand{\N}{\mathbb{N}}

And put it anywhere before you plan to use the shortcut, I'd assume. I usually just do it after I list my packages.

(I've never sat down and read a full guide for latex, so maybe this is common knowledge, but I never realized it until I saw a prof do it.)
