In these modern times of asynchronous communication and paperless receipts, a person's email inbox can get mighty full. Keeping that influx of emails at bay is a challenge. If you'd like to start unburying yourself and get on the path to inbox zero -- Gmail's keyboard shortcuts can help.
Keyboard shortcuts are not enabled by default, so you'll need to turn them on in settings. Click the gear icon, select Settings and then scroll down under the General tab until you find the Keyboard shortcuts section. Select the Keyboard shortcuts on radio button and then Save changes.
You'll now have access to a variety of shortcuts, such as using the j and
k keys to move up and down the list of emails in your inbox. Find the one
you want and hit o to open it
up.
Keep exploring -- there is a whole world of keyboard shortcuts out there.
