So, you've just imported thousands of emails into your GMail account with the POP function? Well you now have thousands of messages marked "Unread" in your inbox. This is annoying. You could go page by page (25 to 100 at a time) marking your messages as "Read," but here is the "All in one swoop" approach:

-In the search box, enter the following "is:unread" (without the quotes).
-In the "Select:" area, Click "All"
-A new link appears, Click it: "Select all conversations that match this search"
-Click the drop down box "More actions..." and select "Mark as Read."
