在按下某个键之前使 Macintosh 显示屏空白的最简单方法是什么？
使 Macintosh 屏幕消隐（全黑）并仅通过击键（而不是鼠标移动）取消消隐的最简单方法是什么？我很乐意追求这些实现中的任何一个：
- 创建一个完全自定义的程序，使屏幕空白（或关闭显示器）并等待击键。 （一个简短的 gcc/g++ 程序会很棒......）
- 创建（或定位）一个忽略鼠标事件的标准“系统偏好设置”屏幕保护程序
- 一些使现有屏幕保护程序系统忽略鼠标事件的配置技巧
- 第三方应用程序，免费或商业广告
不需要精美的屏幕保护程序图形 - 只需一个空白屏幕。
我是一位经验丰富的开发人员（Linux、Windows），但从未为 Mac 编写过代码。非常感谢。
What is the simplest way to blank a Macintosh screen (completely black) and unblank it only on keystroke (not mouse movement)? I'm happy to pursue any of these implementations:
- Create a completely custom program that blanks the screen (or turns off the display) and awaits a keystroke. (A short gcc/g++ program would be great....)
- Create (or locate) a standard "System Preferences" screensaver that ignores mouse events
- Some configuration trick that makes the existing screensaver system ignore mouse events
- A third-party app, free or commercial
No fancy screensaver graphics wanted - just a blank screen.
I'm an experienced developer (Linux, Windows) but have never written for the Mac. Thank you very much.

根据您对 CajunLuke 答案的评论，为什么不在不使用时完全关闭屏幕亮度呢？据我所知，所有Mac键盘都有屏幕亮度按钮，因此您可以在需要时使用它们快速打开/关闭屏幕亮度。
Based on your comments on CajunLuke's answer, why not just turn off screen brightness completely when not in use? As far as I know, all Mac keyboards have screen brightness buttons, so you could use them to quickly turn on/off screen brightness when you want to.
Control-Shift-Eject 应该可以完成你想要的操作。如果您设置了屏幕保护程序密码，它也会要求输入该密码。
Control-Shift-Eject should do what you want. If you have a screensaver password set up, it'll ask for that, too.
