Never lift my hands from the keyboard home position.

There isn't a good catagorie to submit this request. But it would be so wonderful if I could log in by typing my credentials and then tap the return key on my keyboard like every other service one logs into online. It is frustrating to always have to lift my hands off the keyboard and move the cursor to the "login" button and press a button on the mouse or trackpad. Bad way to start my work day. This is really basic. Please implement this simple feature. Thanks!
