     2) my_paste_modifiers  : Functions to modify text when it is pasted into.   
                              (only for pasted text)
     3) my_custom_triggers  : Functions to be executed after typing certain text.

  // Function signature: Takes no arguments.
  //                     Should do whatever needs to be done 
  //                     (inserting a random greeting in this case)

  //                     Should return true if the last typed letter is intended
  //                     to appear. For example, the '?!' function deletes the
  //                     character immediately before '?', but also lets the
  //                     '!' to appear. So typing "reallyy?!" would actually
  //                     result in "really!".
