Params title is the name of window whose contents we want to update.
Action Refreshes the contents of the window displaying the object at addr.
This is an advanced Frontier verb of primary interest to implementers and advanced scripters. It is not necessary to understand it to use Frontier effectively for most tasks. Normally, windows update themselves. But there are times when you may wish to explicitly update a window's contents. This will most likely happen only with a window containing a picture object which in turn contains expressions.
