Users accessing the web using only a keyboard may have a physical disability that makes typing very difficult. They may have a condition such as cerebral palsy or Parkinson's disease which causes their hands to shake. Or they may have one button access activating a switch or using a puff and sip device.

By offering suggestions, spelling corrections or even the ability to go back and fix errors you will help improve their user experience.
