email data from several selected records

I want the user to check several records in a View with the checkbox that shows on the left. Then choose an Action from the Dropdown on top of the view to email the information from each marked record.

How do I test if a record was checked? What is the best way to loop thru all the records looking for the checked records?

Thanks
