If you have solved question 2, you will know that a face is a complex object with many facets. The actor(s) it contains are stored in one facet, which is an object with one field per event. Suppose we have the following code for a button:

Click the button and then scroll down to the end of the console output, you will find the following:
actors: make object! [ on-click: func [face [object!] event [event! none!]][print bt]]
We'll apply it in the following two sections.
