Does this sound familiar? You start to watch a video on YouTube, and want to pause it. So you press the spacebar on your keyboard, but rather than pause the video, you randomly jump down the page instead.

这听起来很熟悉吗？ 您开始在YouTube上观看视频，并希望将其暂停。 因此，您按下键盘上的空格键，而不是暂停视频，而是随机跳下页面。

If you’re like me, then you probably find this thoroughly aggravating. As it turns out, YouTube has its own keyboard shortcuts that solve this problem–albeit a little messily. But let’s start by talking about that annoying spacebar.

如果您像我，那么您可能会发现这种情况更加恶化。 事实证明，YouTube拥有自己的键盘快捷键，可以解决此问题-尽管有点混乱。 但是，让我们从谈论那个烦人的空格键开始。

为什么按下空格键会跳下页面？ ( Why Does Pressing the Spacebar Jump Down the Page? )

You’ve essentially been programmed to use the spacebar through a gradual and likely accidental form of Behavioral Engineering . Most, if not all, media players available today, including video streaming services like Netflix and Amazon Instant Video, utilize the spacebar as the shortcut for playing and pausing media. It’s hard to tell where this started, but in my research, I found references to both RealPlayer and QuickTime as far back as 2001. During that time, other media players were using Ctrl+P as the method to control this function but eventually practically all media players adopted the spacebar convention.

实际上，您已经被编程为通过 行为工程的 一种逐渐且可能是偶然的形式来使用空格键。 当今大多数(如果不是全部)可用的媒体播放器，包括Netflix和Amazon Instant Video等视频流服务，都使用空格键作为播放和暂停媒体的快捷方式。 很难说这是从哪里开始的，但是在我的研究中，我发现早在2001年就同时引用了RealPlayer和QuickTime。在此期间，其他媒体播放器都使用Ctrl + P作为控制此功能的方法，但实际上几乎所有媒体播放器采用了空格键约定。
