create email hyperlink in form

How do I create an email hyperlink in a form? MS Access has a hyperlink data format that makes it easy.
I have a main form with patient demographics. One of the text boxes is for the patient's email address. I want to be able to open my email program by just clicking on the text (or an associated button) with the To: field in the email program already filled in. This sort of action is automatic from a Calc file. OO Calc automatically recognizes an email address entered into a cell so later I can just click on the email address and what I describe above happens.
Any help would be appreciated. Of note, I am just learning macro programming and am not very good at it yet.
