Lesson 23. Keyboard Control

So far, you have developed projects that let users control the actions of a movie based on mouse movements or mouse clicks on the stage. In this lesson, you will give users a way to control actions using the keyboard. Keyboard control is useful in a wide variety of projects. For example, in some games it may be faster and easier to control events using the keyboard rather than a mouse. Keyboard control can even be essential in projects such as kiosk applications, where a mouse is not available.
