Create Help Button on Access...

Hi

I hope someone can help me. I think it's something very simple but I don't see how to do it.

I want to make a Help Button in my database that when I or the user press it, open like a popup or similar a word, pdf document with instructions to help the user on the applications functions etc.

I'm really looking forward to do this because it would help to improve my application.

Thanks to anyone that can help me in this manner.

Regards!
