So, for months now I've been plagued by 3 unread messages in my Gmail box. I couldn't find the darn things and the idea of surfing page by page through 12 years of emails just didn't seem practical.

So, here's the fact I learned today. If you want to view all of your unread emails, from all filters, at once, simply type "is:unread" (without the quotes) into your search field and click  Search Mail. Then just coast through the list. I'm so happy!!!
