The "Halo"

The "Halo" lets you interact with any object you can touch (i.e., any morph). Alt-Click on a morph to bring up its halo.

A star morph with its halo

Successive alt-clicks will transfer the halo to the next morph in the hierarchy - experiment with this. Mouse over the various halo handles and read the help-balloons that will pop up to explain what each handle does. The name of the object that currently bears a halo will be seen at the base of the halo (and a click on the name will let you edit it.)
