Hello. I have a mailto link that populates the body of an email and I would like the cursor to automatically be placed two lines below the body copy.

For example, this link
HTML Code:
<a href=test@test.com?subject=Test Subject&body=TO: Test Person %0D 123 Test st. %0D United States>email us</a>
will produce something like this in the new email composition:

TO: Test Person
123 Test st.
United States
How can I get the cursor to be two lines below United States, so people can start typing their email there?

Can this be accomlished with php or javascript easily?

I am using outlook, and the majority of my users who will click this link will be using outlook also, if that helps.

Thanks for any help you can provide.
