Duotone: How to modify/add links at top of page above photo

Hello, using latest version of Duotone to produce http://www.thelifeinaday.com. The default theme includes two links above the photo, one called “Archive” and one called “Sample Page” which I changed to “About” and populated with useful content via the “Pages” menu in the Dashboard.

I want to add more buttons in that menu bar, like “Home” and “Contact”. But how do I do that? “Home” is not a page, just a redirect back to home. Contact could be a page or could be just a mailto: link.

These are not pages so the “pages” section of the dashboard doesn’t seem appropriate, yet neither does the “menu” section. The solution is probably in modifying the CSS, but where?

Thanks all for your time and advice!!
