Searching Exercises
===================

   * Write an interactive function that searches for a string.  If the
     search finds the string, leave point after it and display a message
     that says "Found!".  (Do not use `search-forward' for the name of
     this function; if you do, you will overwrite the existing version
     of `search-forward' that comes with Emacs.  Use a name such as
     `test-search' instead.)

   * Write a function that prints the third element of the kill ring in
     the echo area, if any; if the kill ring does not contain a third
     element, print an appropriate message.
