		value - the value to set, cannot contain semicolons

		options - an object representing the Cookie options. See Options below. Default values are stored in Cookie.options.

		domain - the domain the Cookie belongs to. If you want to share the cookie with pages located on a different domain, you have to set this value. Defaults to the current domain.

		path - the path the Cookie belongs to. If you want to share the cookie with pages located in a different path, you have to set this value, for example to "/" to share the cookie with all pages on the domain. Defaults to the current path.

		secure - Stored cookie information can be accessed only from a secure environment.

	options - an object. See options Below.



Options:

	maxTitleChars - the maximum number of characters to display in the title of the tip. defaults to 30.

	showDelay - the delay the onShow method is called. (defaults to 100 ms)

	hideDelay - the delay the onHide method is called. (defaults to 100 ms)

	offsets - the distance of your tooltip from the mouse. an Object with x/y properties.

	fixed - if set to true, the toolTip will not follow the mouse.

	

Events:

	onShow - optionally you can alter the default onShow behaviour with this option (like displaying a fade in effect);
