该代码片段展示了在UnrealEngine中如何通过监听CTRL+S快捷键实现着色器的即时更新。当按下CTRL+S时，程序会等待一小段时间以确保文件写入完成，然后重新加载所有着色器，实现简单的着色器热重载功能。

	// Listen to CTRL+S for shader live update in a very simple fashion (from http://www.lofibucket.com/articles/64k_intro.html)
	static ULONGLONG lastLoadTime = GetTickCount64();
	if (GetAsyncKeyState(VK_CONTROL) && GetAsyncKeyState('S'))
	{
		const ULONGLONG tickCount = GetTickCount64();
		if (tickCount - lastLoadTime > 200)
		{
			Sleep(100);					// Wait for a while to let the file system finish the file write.
			loadShaders(false);			// Reload (all) the shaders
		}
		lastLoadTime = tickCount;
	}
