title: Reading numpad symbols under Mono
body: <p>I am developing a console application, that should listen for digits from a numpad keyboard in both num lock states - on and off. The application is running on Raspberry Pi with Arch Linux and Mono. Since I did not found a way, that is compiling under Mono, to permanently turn numlock on, I am using the following method to convert num pad commands to digits:</p>
  
  <pre><code>private string ReadNumPadSymbol(ConsoleKeyInfo keyInfo)
      {
          char editedSymbol;
          switch (keyInfo.Key)
          {
              case ConsoleKey.Insert:
                  editedSymbol = '0';
                  break;
              case ConsoleKey.End:
                  editedSymbol = '1';
                  break;
              case ConsoleKey.DownArrow:
                  editedSymbol = '2';
                  break;
              case ConsoleKey.PageDown:
                  editedSymbol = '3';
                  break;
              case ConsoleKey.LeftArrow:
                  editedSymbol = '4';
                  break;
              case ConsoleKey.Clear:
                  editedSymbol = '5';
                  break;
              case ConsoleKey.RightArrow:
                  editedSymbol = '6';
                  break;
              case ConsoleKey.Home:
                  editedSymbol = '7';
                  break;
              case ConsoleKey.UpArrow:
                  editedSymbol = '8';
                  break;
              case ConsoleKey.PageUp:
                  editedSymbol = '9';
                  break;
              default:
                  return String.Empty;
          }
          return editedSymbol.ToString();
      }
  </code></pre>
  
  <p>It works as expected under Windows, but under Linux, the method returns empty string, when the "5" button is pressed. For some reason it does not enters the ConsoleKey.Clear case. Is there a fix for this?</p>
  
  <p>Thanks!</p>
