title: How can I use the keyboard arrow keys to move a character across a grid?
body: <p>So I have created code for a grid that looks like this :</p>
  
  <pre><code>- - - - - - - - - -
  - - - - - - - - - -
  - - - - - - - - - -
  - - - - - - - - - -
  - - - - - - - - - -
  - - - - - - - - - -
  - - - - - - - - - -
  - - - - - - - - - -
  - X - - - - - - - -
  - - - - - - - - - -
  </code></pre>
  
  <p>Co-ordinates are accessed by calling <code>my_grid.Grid[x_coordinate][y_coordinate]</code>, and new characters can be placed anywhere there (as shown by the 'X' with coordinates <code>[1][1]</code>)</p>
  
  <p>I want to be able to move this character in any direction using arrow key inputs, without using the 'Enter' key afterwards if possible.</p>
  
  <p>What is the best way to do this?</p>
