////////////////////////////////////////////////////////////////////////////////
//
// This function will give any text input that invokes it via onKeyPress the
// ability to submit the form when the enter key is pressed, even if it is one
// of many text inputs in the form.
//
// If NN4, the character code is contained in NN4's which property.  Otherwise
// if IE, the character code is contained in IE's keyCode property.
//
// If the character code equals ascii 13 (enter key), then submit the form.
// NOTE:  Before submitting, the validateSearchForm() method is called.  All
//        search forms must therefore override this method for validating.
//        Calling submit directly does not invoke and onsubmit() calls, so this
//        is the workaround used.  In the future, eventListenerList() could be
//        used when browsers fully implement Dom Level 3 Events.
