Then I would like to remind you of some often overlooked features.
Keyboard Shortcuts
You will need to turn these on via Settings > General Tab > Keyboard Shortcuts. Then you can hit the “?” key to see all the shortcuts that are available. My favorites are the “j” and “k” key to move up and down your list of emails (VI editor anyone) and then you can just hit the “Enter” key to display the message you want to read. Once in an email, you can hit “#” to delete the email or hit “g” then “i” to go back to the inbox. It will seem a bit strange at first to navigate via the keyboard instead of a mouse but if you get a lot of Gmail, reading and deleting via the keyboard shortcuts will save you a lot of time.
Themes
Tired of the same old look and feel of Gmail? You can now specify a Theme to spice up your experience via Settings > Themes tab. Some of the themes such as Beach will even change throughout the day as the Sun rises and sets. If you are a Google Apps user and have your domain email hosted by Google then unfortunately the Themes tab will not be available. Strange but true.
Video Chat
You can now do a Video Chat (think Skype) to another Gmail user. You will need to download a browser plugin and then you are all set to chat with another Gmail user without having to leave Gmail. More complete information on this feature can be found here.
Gmail Labs
Are you the experimental type of person? Gmail Labs are little tweaks and shortcuts for Gmail that are still being worked on by Google and may or may not be eventually incorporated as a standard feature:
Gmail engineers come up with new ideas all the time. Gmail Labs is our place to try them out and get your feedback. None of these features are really ready for prime time yet, so they may change, break or disappear at any time
Click on Settings and the Labs tab and you will see a wealth of fun features to try out. If you turn on any Labs features you will see a beaker icon just to the right of you Gmail name on the upper right hand side. Sorry Google Apps domain users, no Labs tweaks for you.
