+=== Function: ONEKEY ===
+    Syntax: onekey (keylist, echo) : string
+    This function asks the user to input a character but accepts only input
+    from the user that matches a character in the keylist.  If echo is True
+    the function will print the character to the terminal.
+    Example:
+      ch = onekey(chr(13) + "APQ", True);
+      if ch == 'A':
+           writeln("User pressed A")
+     The above example prompts the user to enter one of the keys A, P, Q or
+     the ENTER key (ASCII #13).  Because echo is True, it will prompt the
+     character to the terminal before returning the key that was pressed.
+     User input for this function is not case sensitive.
