在科技的演进中
In the evolution of technology,
东西被淘汰是很自然的
it’s only natural that things become obsolete.
科技在某个节点会渐渐退出大众视野
In some point of their existence, technologies fall out of the big picture,
被新的科技取代
and get replaced by newer ones that
这些新科技往往更可靠 更快 更方便
are often more reliable, faster, and convenient than their predecessors,
或者仅仅更适合新的生产方式
or simply more intone with the new ways things get done.
这种事情在电脑工业中时刻上演
In the computer industry, this is something that happens all the time.
这个领域不像绘画 一幅画可以流传千年
This is not a field where one paints a painting that will be looked at for centuries,
或者像修教堂 教堂受人敬仰
or builds a church that will be admired
可以让人仰望几个世纪
and us, you know, looked at an astonishment for centuries.
你懂的 这领域 一个人在十年内完成一个人的工作量
You know, this is a field where one does one’s work in 10 years.
那很落后 并且10到20年之内不会有用
It’s obsolete, and really will not be usable within 10 or 20 years.
事物更新换代相对较快是电脑科技的本质
The natural property of computer technology is that things get old relatively fast.
因此 如今的孩子从不知道 拨号上网的机械声
And it is because of this property that kids these days will never have to experience things
窗口错误的满屏乱码 或者软盘是什么
like the robotic sound of dial-up internet, the psychedelic patterns of error windows, or floppy disks.
如果你知道这些
Now, if you’ve been around long enough to experience these things,
那你现在可能在傻笑
you might be smirking.
如果你用电脑 不管你信不信
But believe it or not, if you’re a PC user,
有些东西一直保持着电脑买来时的样子
right now in front of you is something that has been there for as long as you had that computer.
如果被问起它的功能
And if somebody asks you what it does,
你不一定知道答案
you probably wouldn’t know the right answer.
所以 这东西到底是什么?
So, what am I talking about?
它就在你面前
Well, it’s right in front of you.
靠近点看 看下面
Take a closer look. Down here.
它在键盘上
It’s on your keyboard.
这个孤独的小按键 名为滚屏锁定
A lonely little key called the Scroll Lock.
若有人问起它的功能
If somebody just asked you, “what does it do?”
你的第一反应可能是
Off the top of your head,
跟滚动有关吧
you would probably say it does something for scrolling.
具体呢? 我是说无论开关屏幕都能滚动
But what? I mean you can scroll whether it’s on or off.
但它具体是做什么的呢?
But what does it do specifically?
即使是以前 人们也不懂这个按键到底有什么用
Even back in the day, people didn’t understand why the heck the key was there.
20世纪80年代早期 《电脑》杂志
In an interview from the early 1980s,
《电脑》杂志对键盘制造商Key Tronic一位总经理进行采访时问道:
PC magazine asked an executive of keyboard manufacturer Key Tronic,
“滚动锁定键的功能是什么?”
“what was the Scroll Lock’s purpose?”
总经理回答说:
To which the executive replied,
“我不知道 但我们生产的时候也安上去了”
“I don’t know, but we put it in ours, too.”
那么 这个按键最初的功能是什么?
So, what was the initial purpose of the key?
它又是如何产生的呢?
And where does it actually originate from?
滚屏锁定键问世于IBM的初代电脑键盘
The Scroll Lock dates back from the original IBM PC keyboard,
并为日后其他键盘制造商所沿用
and as a feature that other keyboard manufacturers simply adopted in the years after.
它的初始设计是调节方向键
It was initially intended to modify the behavior of the arrow keys.
更具体一点
More specifically,
它还能切换两种不同的滚动模式
it would toggle between two different modes of scrolling.
开启滚动锁定
When the Scroll Lock was on,
方向键能滚动整个窗口的内容
the arrow keys would scroll the content of the entire window;
关闭的时候 方向键只能移动光标
when it was off, the arrows would only move the cursor.
作为少有的使用该键的现代程序 微软的Excel表格
We can see an example of the Scroll Lock in modern use in Microsoft Excel,
向我们展示了滚屏锁定键的现代运用
which is one of the very few modern programs that still utilize this function.
关闭滚屏锁定
When the Scroll Lock is turned off,
用上下方向键或者鼠标滑轮
using the up and down arrow keys as well as the scroll wheel on the mouse,
只能完成不同单元格之间的移动切换
only causes the selection to move between individual cells.
开启滚屏锁定
But when the Scroll Lock is turned on,
用方向键和滑轮可以滚动整个屏幕
using the arrows and the scroll wheel cause the entire page to scroll.
但这不是滚屏锁定键唯一已知的用处
But this is not the only thing the Scroll Lock is known to be used for.
根据操作系统和应用的不同
Depending on the operating system or application that is utilizing it,
它有不同的功能
it can have different functions.
Linux系统中
In Linux,
滚屏锁定键能冻住和解冻操作台的输出
the Scroll Lock can be used to freeze and unfreeze output in the Linux console.
从Windows 2000开始
Starting from Windows 2000,
微软的Windows NT系列能用滚屏锁定键进行调试
the Microsoft Windows NT family can utilize a Scroll Lock for debugging purposes.
其他系统中
In other systems,
它能加速检测 复制粘贴
the Scroll Lock is known to be used for boot Diagnostics, copy pasting,
并和其他按键合用
and in combination with other keys,
甚至能替代取消暂停键
even as an alternative for the Break Pause key.
然而 这些功能要么很少用
However, these are all functions that are either extremely uncommon,
要么能被代替
or have alternative ways of being achieved.
所以大对部分用电脑的人来说
So for the great majority of PC users,
滚屏锁定键是没用的
the Scroll Lock key is simply unnecessary.
许多制造商仍保留该键的原一个因 可能是软件老化
One possible reason why a lot of manufacturers is still included on their keyboards may be legacy software.
但是
But then again,
那并不能阻止大量旧科技的没落
that hasn’t stopped a ton of other old technologies from falling out of the big picture.
有趣的是 2014年 记者雷加特·范·德·博格写了篇文章
It’s interesting how journalists Regardt van der Berg put it in an article from 2014,
在所有话题中唯独就谈到了滚屏锁定键
in which he among other things wrote about the Scroll Lock.
人类进化时
In human evolution,
祖先给现代人身上留下了没用的部位
there are leftover pieces from our ancestors that have no real use in the body today.
科技领域 也有些残留品 尤其在许多电脑键盘上
In technology, we see a few of those vestigial leftovers, particularly on many computer keyboards.
但说起滚屏锁定键
But when it comes to the Scroll Lock,
祖先都显然不知道它的具体用处
it would appear that not even those ancestors knew exactly what it would be used for.
IBM自己的个人电脑文件都把它叫做不活跃键
IBM’s own PC documentation called it an inactive key.
有人甚至说它毫无用处
And someone even as far as stating that it has no use.
1982年 《个人电脑》杂志这样写道:
In 1982, PC magazine put it like this:
滚屏锁定键看起来能撤销数字锁定键的作用
The Scroll Lock key is placed as if it would reverse the effect of Num Lock,
但并不是
but it does not.
事实上
As a matter of fact,
滚屏锁定键现在没用
ScrollLock has no present use;
它是留给未来的程序员的 当它可以用时
it has been provided for future use by programmers who want to make screenfuls of data
程序员门可以按方向键来上下左右移动
scroll up, down, or sideways when the arrow keys are pressed
满屏幕的数据
while ScrollLock is in effect.
有人认为 知道滚屏锁定键当时没用
For ScrollLock, someone might think knowing how it went from something that had no current use
知道它是前人剩下的东西这些事 同样的是无用的
to left over from our ancestors that again has no use.
但你我都知道它的确有用
But, you and I know it indeed did have its purpose.
而且还一直存在着
And nevertheless, it’s still here,
这不像其他过时的科技 报废期一过 很快就消失了
as opposed to other obsolete technologies that quickly fade away after their expiration date is passed.
滚屏锁定键好像打算在阳光里再待5分钟
It’s almost as if it’s waiting for another 5 minutes in the sun.
这样想的话 有点苦乐参半
It’s kind of bittersweet when you think about it.
说道宇宙物体
And speaking of cosmic objects,
也许这个类比是结束这段视频最好的方式
maybe the best way to end this video is through this analogy.
当你通过望远镜看到遥远星系中一颗闪亮的星星时
When you look through a telescope, and see a shining star from a galaxy far far away,
很有可能你只是看到了它传播的光 星星本身早就消失了
there’s a great possibility that you’re just seeing the light traveling from a star that is long gone.
某种程度上 滚屏锁定键有点像这样
In a way, the ScrollLock is something similar.
被遗忘的纪念碑闪烁微光 这光代表着电脑的发展史
Our forgotten monument shining a little light of computer history that made its way into the present,
一路前行
despite all odds.
