	HotKey -- create a commodity triad. (V36)

	filterObj = Hotkey(description,port,id);

	CxObj *HotKey(STRPTR,struct MsgPort *,LONG);

	This function creates a triad of commodity objects to accomplish a
	high-level function.

	The three objects are a filter, which is created to match by the call
	CxFilter(description), a sender created by the call CxSender(port,id),
	and a translator which is created by CxTranslate(NULL), so that it
	swallows any commodity input event messages that are passed down by
	the filter.

	This is the simple way to get a message sent to your program when the
	user performs a particular input action.

	It is strongly recommended that the ToolTypes environment be used to
	allow the user to specify the input descriptions for your application's

	description - the description string to use for the filter in the same
		      format as accepted by commodities.library/SetFilter()
	port - port for the sender to send messages to.
	id - id of the messages sent by the sender

	filterObj - a pointer to a filter object, or NULL if it could
		    not be created.

	CxFilter(), CxSender(), CxTranslate(),
	commodities.library/CxObjError(), commodities.library/SetFilter()
