## Overview

The Keyboard unit implements a keyboard access layer which is system independent. It can be used to poll the keyboard state and wait for certain events. Waiting for a keyboard event can be done with the GetKeyEvent function, which will return a driver-dependent key event. This key event can be translated to a interpretable event by the TranslateKeyEvent function. The result of this function can be used in the other event examining functions.

A custom keyboard driver can be installed using the SetKeyboardDriver function. The current keyboard driver can be retrieved using the GetKeyboardDriver function. The last section of this chapter demonstrates how to make a keyboard driver.
