# Keypress Display Plugin

The keypress plugin shows the names of all currently pressed input items on screen using MAME's pop-up message overlay. It is useful for gameplay recording and tracing player actions, as well as diagnosing input mapping issues.

Enable the plugin using the plugin option on the command line:

    mame <system> -plugin keypress

While the plugin is active, any pressed keys, buttons, or other input items will be displayed as a space-separated list at the bottom of the screen. The message clears automatically when all inputs are released.
