How To Browse Only the Unread Messages

Tip from: http://www.dailyblogtips.com/gmail-tip-how-to-browse-only-the-unread-messages/

If you have tons of unread messages, or as in my case if there are some messages which you marked as unread to be read later and now those messages are buried deep under pages and pages of "read" messages, you would have to run through all the previous pages in order to find those unread messages. 

There's a better way to do this: 

Search for "label:unread" on the Gmail search box, this will filter only the unread messages.

You can also use "label:unread label:MY_LABEL" in the search box to search through only unread messages in MY_LABEL
