Hello,

I am a little confused about LaTeX in general, but let me se if I can get this right:

From what I can understand, it is a way that a user is able to enter mathematical expressions by certain keystrokes, and have them display with some consistency under most platforms.

Now, it appears to be waay more powerful than this, and I have heard that people can "program" LaTeX? What does that mean exactly?

I'm just looking for an introduction, or a link to one if necessary.

Thanks!
