HyperTalk is the HyperCard scripting language. It lets you write
English-like statements that respond to events (such as when the user
clicks a button or goes to a new card).
In HyperTalk, responding to an event is called handling the event. As a
scripter, you will write a specific handler for each event that you want
your stack to handle. A collection of handlers is called a script.
