Right clicking many files and emailing

[omar]

OMG, I can use AHK to email using Gmail! (Only recently discovered!)

I would love to be able to right click many files and send them as an attachment.
How can I do this in AHK?
How do I pass as arguement the right clicked files?

Doesn't have to be right click of course
I have a menu I use for AHK, I could add another menu item, - so all I need to know is how to geet the full path listings of the selected items.

Thanks.
