Here’s a useful USB add-on gadget called the Gmail Keypad for those who use GMail frequently. Instead of using conventional keyboard shortcuts in Gmail’s web application, all you need is to plug this into your PC’s USB port and you’re set to blaze through emails utilizing the 19 pre-programmed hotkeys on the keypad. Looks like a great time-saving and efficiency boosting PC peripheral. $19.99, ThinkGeek.
