Ever happened to have lots of unread emails in your Gmail which you do not intend to read? Well, it happens to me often. As at the moment I have 180 unread emails across several pages; i.e. I have to click next, next, next to keep going through the unread emails.
To list unread emails only, type
is:unread in the email search bar. All unread emails will be listed. Then click on the drop arrow, on the left, and select
More and then
Mark as read.
That's it. Done!
