Parameter 			Possible values 	Default 	Description
header 				Any character 		blank 		Specifies the header text of the tooltip
body 				Any character 		blank 		Specifies the body text of the tooltip
fixedrelx 			Any integer 		N/A 		Forces the X-coordinate of the tooltip to stay fixed (offset is relative to the annotated HTML element)
fixedrely 			Any integer 		N/A 		Forces the Y-coordinate of the tooltip to stay fixed (offset is relative to the annotated HTML element)
fixedabsx 			Any integer 		N/A 		Forces the X-coordinate of the tooltip to stay fixed (X is an offset relative to the body of the HTML document)
fixedabsy 			Any integer 		N/A 		Forces the Y-coordinate of the tooltip to stay fixed (Y is an offset relative to the body of the HTML document)
windowlock 			on / off 			on 			Make tooltip stick to side of the window if user moves close to the side of the screen.
cssbody 			Any defined 		style 		class 	Built in styles 	Specifies CSS class for styles to be used on tooltip body.
cssheader 			Any defined 		style 		class 	Built in styles 	Specifies CSS class for styles to be used on tooltip header.
offsetx 			Any integer 		10 			Horizontal offset, in pixels, of the tooltip relative to the mouse cursor.
offsety 			Any integer 		10 			Vertical offset, in pixels, of the tooltip relative to the mouse cursor.
doubleclickstop 	on / off 			on 			Specifies whether to halt the tooltip when the user double clicks on the HTML element with the tooltip.
singleclickstop 	on / off 			off 		Specifies whether to halt the tooltip when the user single clicks on the HTML element with the tooltip. - if both singleclickstop and doubleclickstop are set to "on", singleslclickstop takes preference.
requireclick 		on / off 			off 		Specifies whether the user must first click the element before a tooltip appears. Intended for use on links so that information appears while the link is followed.
hideselects 		on / off 			off 		Specifies whether to hide all SELECT boxes on page when popup is activated.
fade 				on / off 			off 		Specifies whether to fade tooltip into visibility.
fadespeed 			Number between 		0 			and 1 	0.04 	Specifies how fast to fade in tooltip.
delay 				Any integer 		0 			Specifies delay in milliseconds before tooltip displays.
