# Automatically define macros in LyX documents

I'm using LyX all the time and over the last 2 years I've accumulated some very handy macros for my lecture notes. As it is today, every time I start a new document, I copy and paste the macros from one of my other documents. Is it possible, somehow, to automatically load macros for all files?

(I asked this on SO a while back and got no answers. I hope in this new home I'll get a response).

This is useful for (La)TeX users in general. I have a lot of common things in my own file, such as `\newcommand{\Integers}{\mathbb{Z}}` and such.
