//checkKey(keyEvent) is an event handler for the onKeypress event. It submits the form 'f1' when the
		//'Enter' key is pressed. It takes a reference to an event as an argument (keyEvent). Navigator uses
		//this reference directly, MSIE ignores it and gets the event from the window in which the event fired.

															// We have to check for both because Netscape 4.05 for Windows thinks 
															// that ENTER == RETURN == Char(13). This means that if you'd still like
															// to have only the ENTER key submit the form in the other browsers,
															// you'd have to make this condition check the browser and behave in this
															// (stupid) way only for Win32 Netscape 4.05.
