Google has released new Google Labs improvements for GMail.

My favorite new feature is mouse gestures.  Dragging the mouse right or left while holding down the right button will move to the next or previous message, respectively.  Here’s a screenshot:

To enable mouse gestures, which currently work on Firefox 2+ and IE click “Settings” when signed into GMail then go to the labs tab on the right.  Scroll down to Mouse Gestures and click enable.  Be sure to click “Save changes” on the bottom or it woln’t work.  Dont’ forget to check out the other GMail Labs features!!
