title: Repeated input by holding down key in Emacs
body: <p>How to lower/remove the delay, and speed up the insertion of additional keys on holding down a key?</p>
  
  <p>For instance: if you want to type a long <code>"ffffffffffffff"</code> sequence, when you do not care how many f's exactly, it takes quite some time when holding down the <code>f</code> to get the result. </p>
  
  <p>There is a quite long initial delay, and the speed of the f's appearing after the delay is not the fastest either. Does anyone know which parameters are involved, and how to alter them?</p>
