// Here we define new global configuration variable(s) (as members of the
// predefined "config." class).
// From each of these config variables, wz_tooltip.js will automatically derive
// a command which can be passed to Tip() or TagToTip() in order to customize
// tooltips individually. These command names are just the config variable
// name(s) translated to uppercase,
// e.g. from config. Draggable a command DRAGGABLE will automatically be
// created.

//===================  GLOBAL TOOLTIP CONFIGURATION  =========================//
config. Draggable = false		// true or false - set to true if you want this to be the default behaviour
config. DragCursor = "move";	// Any valid CSS cursor name (value), in quotes
//=======  END OF TOOLTIP CONFIG, DO NOT CHANGE ANYTHING BELOW  ==============//

// here tt_drag, is unique amongst the extensions available for wz_tooltips.js):
