September 15, 2010, 7:26 AM — On August 30, Google launched (in beta) Priority Inbox for Gmail. The idea is simple: To help you get right to your most important messages. But, of course, there are ways to make it work better, and that's where these tips come in.
In a post on the official Gmail blog, Kristen Lemons offers up this advice for helping Gmail learn which messages should land in the "important" section and how to quickly clear away unimportant messages.

"If Gmail makes a mistake, you can help it learn to better categorize your messages. Select the misclassified message, then use the importance buttons at the top of your inbox to correctly mark it as important or not important."
"For those of you who can't live without keyboard shortcuts, don’t worry, you can use the "+" and "-" keys to adjust importance as well."
One of the features that can help make you more efficient is the ability to archive all of the visible messages in the "Everything Else" section at once. Just click on the down arrow next to "Everything Else" and select the "Archive all visible items" option. If you want to be able to archive even more messages at once, you can increase the maximum number of messages that show in that section from the same drop-down.
