title: 'Shift' + 'enter' only works when the text line is highlighted. How do I change it, so I don't have to highlight?
body: <p>I'm new in Spyder and Python and hope that someone could help me with a very fundamental question.
  I succeed in running a cell (cmd + enter) or running a cell and advance (shift + enter), but only when the textline is <strong>HIGHLIGTHED</strong>.</p>
  
  <p>How do I change it, so I <strong>don't have to highlight every time</strong>?</p>
  
  <p>e.g.: a = 3
  First I have to highlight and then cmd + enter before the variable is defined.</p>
  
  <p>I use Python 3.7 and Spyder 3.2.2</p>
  
  <p>Thank you in advance!</p>
