Introduction

This command simulates the pressing or a front-panel key.

The <numeric_value> is a key code value.

This command puts an entry in the Key Queue (just as any front-panel key press does). The length of the Key Queue is 500.

The keys and their corresponding key codes are listed in the following table.
