title: TAB key not working in scratch buffer of emacs
body: <p>Hitting TAB key while entering text into scratch buffer does not do anything. I would like TAB key to behave exactly as it would in other normal buffers(move point forward by inserting some X number of spaces or insert a TAB character). Could you please help me achieve that? Thank you. </p>
