The Babylon Viewer aims to simplify a specific but common Babylon.js use case: loading, viewing, and interacting with a 3D model.

/**
 * Shared base class for keyboard event blocks (KeyDown / KeyUp).

 * Provides a `key` input filter, output data connections for the key code,
 * key string, modifier states, and a platform-aware `commandOrCtrl` flag.
 * Subclasses only need to set their event type and class name.
