title: C++ Key Input check
body: <p>I am writing a function that gets user input and performs an action according to what the user entered. I am using a case statement that checks what the user entered.  </p>
  
  <p>I am having difficulty seeing if the user pressed home, end, ins and del.  The default variable such as HOME, INSERT, DELETE and END don't seem to have an effect, but the arrow keys do, using LEFT and RIGHT. I am doing this in GNU/Linux. I am not sure what I am doing wrong.  </p>
  
  <p>Any help would be greatly appreciated.</p>
