It turned out that there were no tab completion extension for Chrome and Firefox so we had to write one. Behold the Tab Complete.
Tab Complete adds tab completion features to any input and textarea element it can find without being invasive. Tab completion saves you time from typing and makes you a lot more productive on the web. For example, if you want to type the long "lorem ipsum" text all you have to do is to type just "lorem" and press the tab key. Tab Complete will fill in the rest of the text for you. You can now see how this could be very helpful.
You can create as many tabs as you like. We are starting to use it internally for all our customer support activities in order to respond to your requests even faster than usual. Every little bit of automation adds to the whole lot.
