lazy about tex equations

It's only been a 15 year hiatus but i am now seriously working on a .tex file.

Although I have no problem with brute-force typing in equations, the lazy part of me wishes there were something that would take the MathType output and generate the equation code. Just for efficiency's sake, you know? There are a lot of equations.

I found this thing, which helps. You have to click in the symbols, but for a beginner like me, it's a good way to learn the syntax.
