Linux 黑话解释：Linux 中的 Super 键是什么？
======
![][0]
> 在本次 Linux 黑话解释系列的这一篇，我们会一起来探索 Linux 中的 `Super` 键（或称其为 `Meta` 键）。
当你在网上浏览 Linux 教程时，你可能会遇到 “`Super` 键” 这个术语，对于 Linux 的初学者来说，这可能会引起混淆。
概括地说，如果你的电脑预装了 Windows，那么带有 Windows 标志的 `Windows` 键就是 `Super` 键。
如果你使用的是苹果电脑，那么带有 `⌘` 符号的 `command` 键就是你的 `Super` 键。
![下面这个就是你的 Super 键（或者 Meta 键）][1]
很简单吧？
但是，为什么要将其命名为 `Super` 键呢？毫无疑问，背后一定有一些有趣的故事。
那么，让我们一起按下 `Super` 键，发掘更深层次的故事吧。
### Super 键背后的想法
它首次出现在 “space-cadet” 键盘中，这款键盘是在 1978 年为 [Lisp 机器][2] 设计的，其主要目的是用来模拟 `Meta` 键。（LCTT 译注：这款键盘的独特之处在于它设有七个修饰键，包括 `Shift`、`Control`、`Meta`、`Super`、`Hyper`，用户可以通过组合这些修饰键与其他键来输入更多的字符和命令，它对现代计算机键盘的发展产生了重要影响。）
`Meta` 键在 Emacs 编辑器中是非常重要的一个部分，但在当时的现代键盘中却未能配备实体的 `Meta` 键，因而人们常常通过不同的按键绑定来模仿其功能。
`Super` 键的引入，解决了这个问题，由此我们有了一个真实的 `Super` 键。
快进到 1994 年，当时 `Windows` 键首次在 [微软自然键盘][3] 上出现，它被用来迅速打开“开始”菜单。从 1996 年开始，将 `Meta` 键映射到 `Windows` 键成为了普遍的做法。
### Super 键的一般使用情况
当你在 Ubuntu 桌面上按下 `Super` 键时，它会显示活动概览，让你全面了解每个窗口正在进行的活动：
![在 Ubuntu 中按下 Super 键获得活动概览][4]
但你要知道，除了预览正在进行的活动，你其实还可以做更多。
比如，你可以同时按下 `Super` 键和 `Tab` 键，调出应用切换器，从而在正在运行的应用之间切换。
![][5]
下面列举了一些可以利用 `Super` 键的快捷键（在 Ubuntu 23.10 内部测试通过）：
> 📋 如果你在使用的是基于 Ubuntu 的发行版，其中的某些快捷键可能并不会按照预期那样工作，因为发行版维护者可能已经将该快捷键指定为另一个任务。
快捷键 | 描述
---|---
`Super` | 打开活动概览
`Super` + `Tab` | 切换开放应用
`Super` + `D` | 显示桌面（最小化所有窗口）
`Super` + `A` | 打开应用菜单
`Super` + `S` | 显示快速设定
`Super` + `←` | 将活动窗口移至屏幕的左半部分
`Super` + `→` | 将活动窗口移至屏幕的右半部分
`Super` + `↑` | 最大化活动窗口
`Super` + `↓` | 最小化活动窗口
`Super` + `L` | 锁定屏幕
这些操作实在太方便了，对吧？
### 通过快捷键提高生产效率

我希望这篇文章能给你带来宝贵的信息，使你对 Super 键有更深入的了解 ;)

What is Super Key in Linux?
======
While reading Linux tutorials on the internet, you'd come across the term 'super key' and if you are a beginner to Linux, it may confuse you.
In simplest terms, if your computer came pre-installed with Windows, then the Windows key (with the Windows logo) is your super key.
Whereas if you have an Apple computer, you have to press the command key with the ⌘ symbol as your super key.
![That's your super key \(or meta key\)][1]
Pretty simple. Right?
But what was the reason behind naming it super key? I mean there has to be some interesting story behind it.
So let's press the super key all together to uncover more details.
### The idea behind the super key
It was introduced in The "space-cadet" keyboard, designed in 1978 at MIT for the [Lips machine][2], and mainly introduced to emulate the meta key.
The meta key was a crucial part of the Emacs editor but the modern keyboards of that time did not ship with a physical meta key and it was often emulated using different key bindings.
The introduction of a super key solved this issue by giving a physical super key.
Fast-forward to 1994 when the Windows key appeared for the first time on the [Microsoft Natural keyboard][3] which was used to quickly open the start menu and from 1996, it became common practice to map the meta key on the Windows key.
### Common use cases of the super key
When you press the super key on the Ubuntu desktop, it displays the activities overview, which gives you a peek into what is going on in every window:
![Get activities overview in Ubuntu by pressing the super key][4]
But you can do a lot more than just have a glimpse of ongoing activities.
For example, you can press Super and Tab together to bring the application switcher and switch between running apps.
![][5]
Here are some shortcuts that utilize the Super key (tested in Ubuntu 23.10):
📋
If you are using a distro based on Ubuntu, then some shortcuts may not work as described as the distro maintained may have allocated that shortcut for a different task.
Shortcut | Description
---|---
Super | Open Activities Overview
Super + Tab | Switch between open applications
Super + D | Show desktop (minimize all windows)
Super + A | Open Applications menu
Super + S | Show quick settings
Super + Left Arrow | Snap the active window to the left half of the screen
Super + Right Arrow | Snap the active window to the right half of the screen
Super + Up Arrow | Maximize active window
Super + Down Arrow | Minimize active window
Super + L | Lock screen
Pretty handy. Right?
### Improve productivity with shortcuts
New to Ubuntu? Here are some helpful shortcuts for Ubuntu users:

I hope that it was a superbly informative super article ;)
