Additional Save Button with different redirect

I've been researching how to add an additional save button with a different action and having no luck. I found some info from 2009 using DAL which is now deprecated. Hoping someone has a solution for v10.
I have add and edit pages that need to have the option of being saved as usual (record was added msg) OR the option to save and redirect. I need to handle the save and redirect in the custom button code.
Thank you!
