键盘^(Keyboard)快捷键可以节省大量时间 - 只要您知道它们就在那里。Ubuntu包含快速键盘功能，使任务之间的转换和与任何窗口的交互变得轻而易举。

与任何键盘或热键快捷键^{(keyboard or hotkey shortcuts)}一样，它们需要时间来学习。但它们通常会使您的工作流程更加高效和愉快。

以下是 10 个最受欢迎的Ubuntu键盘快捷键以及它们为何如此酷炫的原因。

• 超级钥匙
• 查看您的系统上安装了哪些应用程序^{(Applications)}
• 最小化^(Minimize)应用程序并显示您的桌面^{(Show Your Desktop)}
• Ubuntu 终端快捷方式
• 锁定屏幕
• 注销或退出
• 文件夹快捷方式
• 开关应用
• 通知托盘
• 运行快速命令

超级钥匙^{(The Super Key)}

您会在Ctrl和Alt键之间的空格键左侧的键盘上找到Super键。它也称为Windows键。有些键盘有两个。

单击Super键将显示活动的概览^(Activities)。此键将显示您当前在计算机上运行的所有应用程序。

您还可以搜索：

• 您当前尚未安装但想要使用的应用程序
• 计算机上的文件  

查看您的系统上安装了哪些应用程序^{(See What Applications Are Installed On Your System)}

有时您可能希望查看系统上安装的所有应用程序（不仅仅是正在运行的应用程序）。

最快的方法是使用快捷键Super+A。下面的屏幕截图向您展示了如何搜索应用程序。

最小化应用程序并显示您的桌面^{(Minimize Applications & Show Your Desktop)}

如果您在尝试完成某事时被桌面杂乱分散注意力，请使用Ubuntu键盘快捷键Super+D。 

不必单击或最小化打开的窗口，只显示您的桌面。

要再次打开所有正在运行的应用程序窗口，请使用相同的快捷方式Super+D。

Ubuntu 终端快捷方式^{(Ubuntu Terminal Shortcut)}

要打开一个新终端^{(open a new terminal)}，请使用Ctrl+Alt+T作为快捷方式。

一直想一想，您可以使用这个Ubuntu键盘快捷键以最小的努力节省正在运行的命令行，例如：

• 清理文件
• 检测硬盘驱动器错误^{(Detecting hard drive errors)}
• 创建 USB 可启动驱动器^{(Creating a USB bootable drive)}
• 远程传输文件
• 修复网络路径问题
• 搜索文件
• 压缩和解压缩
• 执行批量删除

• 检查CPU使用率、HTTP进程和服务器负载
• 释放磁盘空间^{(Freeing disk space)}
• 检查您的服务器 DNS 设置
• 恢复和备份 cPanel
• 管理 MySQL 数据库

锁定屏幕^{(Lock Your Screen)}

出于安全原因，最好在您远离计算机时锁定计算机。锁定屏幕不会停止您正在运行的任何进程或应用程序。

相反，它们将继续在您锁定的屏幕后面运行。要解锁它，您需要输入密码。  

使用Super+L 快捷键快速锁定屏幕。一些系统还使用Ctrl+Alt+L。 

如果您发现自己忘记锁定屏幕，您可以将其设置为在不使用时自动锁定。

注销或退出^{(Log Out Or Exit)}

如果您使用Ubuntu与多个用户并需要在他们之间切换，一种方法是退出您的会话。退出的最快方法是使用快捷键Ctrl+D。

请记住，注销将结束您正在使用的所有会话和应用程序。如果您不想丢失正在处理的内容，请在不注销的情况下切换用户。

单击^(Click)顶部栏上的系统菜单并选择用户名。或者，您可以创建自定义快捷方式。 

您可以在此处了解有关如何设置自定义 Ubuntu 键盘快捷键^{(custom Ubuntu keyboard shortcuts)}的更多信息。

文件夹快捷方式^{(Folder Shortcuts)}

Ctrl+Shift可以轻松创建新文件夹。

要查看任何文件夹的属性，请选择文件夹，然后使用快捷键Alt+Enter。

如果要重命名文件夹，请选择它，按f2，然后输入要使用的新名称。

开关应用^{(Switch Applications)}

一次运行多个应用程序时，使用快捷键组合Alt+Tab或Super+Tab在它们之间切换。

按住Super键并按住Tab键，直到找到要使用的应用程序。当你找到它时释放这两个键。^(Release)

应用程序切换器默认是从左向右移动。如果您喜欢从右向左移动应用程序，请使用快捷键Super+Shift+Tab。 

可以使用 Alt 键代替Super键^(Alt)来^(Super)执行相同的任务。

通知托盘^{(Notification Tray)}

像GNOME^(GNOME)这样的Linux 发行版有一个用于各种活动和系统的通知托盘。这也是您的系统日历所在的位置。

使用键盘快捷键Super+M打开通知区域。

使用相同的键关闭托盘。

运行快速命令^{(Run a Quick Command)}

对于那些不想打开终端的Ubuntu用户，请使用^(Ubuntu)Alt+F2来运行快速命令。

如果您正在使用只能从终端运行的应用程序，这将特别有用。

使用Ubuntu键盘快捷键可以提高生产力并提高效率。知道哪些击键组合会触发您想要执行的操作，将为您节省大量时间。

10 Ubuntu Keyboard Shortcuts To Speed Up Your Workflow

Keyboard shortcuts are great time savers – provided you know they are there. Ubuntu is packed with quick keyboard features that make transitіoning betweеn tasks and interacting with any window a breezе.

As with any keyboard or hotkey shortcuts, they take time to learn. But they will typically make your workflow more efficient and enjoyable.

Here are 10 of the most popular Ubuntu keyboard shortcuts and why they are so cool.

• The Super Key
• See What Applications are Installed on Your System
• Minimize Applications and Show Your Desktop
• Ubuntu Terminal Shortcut
• Lock Your Screen
• Log Out or Exit
• Folder Shortcuts
• Switch Applications
• Notification Tray
• Run a Quick Command

The Super Key

You will find the Super key on the keyboard to the left of the spacebar between the Ctrl and Alt keys. It is also called the Windows key. Some keyboards have two.

Clicking the Super key will display an overview of the Activities. This key will show you all the applications you are currently running on your computer.

You can also search for:

• Applications you don’t currently have installed but want to use
• Files on your computer  

See What Applications Are Installed On Your System

There might be times when you want to see all the applications that are installed on your system (not just those that are running).

The quickest way is to use the shortcut Super+A. The screenshot below shows you how you can also search for applications.

Minimize Applications & Show Your Desktop

If you are distracted by desktop clutter when trying to get something done, use the Ubuntu keyboard shortcut Super+D. 

Rather than having to click or minimize open windows, show only your desktop.

To open all the running application windows again, use the same shortcut Super+D.

Ubuntu Terminal Shortcut

To open a new terminal, use Ctrl+Alt+T as a shortcut.

Think about all the time you can save running command lines with minimal effort using this Ubuntu keyboard shortcut, such as:

• Cleaning up files
• Detecting hard drive errors
• Creating a USB bootable drive
• Transferring files remotely
• Fixing network path problems
• Searching files
• Zipping and unzipping
• Performing mass deletions
• Installing development tools
• Checking CPU usage, HTTP processes, and server load
• Freeing disk space
• Checking your server DNS settings
• Restoring and backing up cPanel
• Managing MySQL databases

Lock Your Screen

For security reasons, it is a good idea to lock your computer when you are away from it. Locking your screen will not stop any processes or applications you are running.

Instead, they will continue to run behind your locked screen. To unlock it, you will need to enter your password.  

Use the Super+L shortcut to lock the screen quickly. Some systems also use Ctrl+Alt+L. 

If you find yourself forgetting to lock your screen, you can set it to lock automatically when not in use.

Log Out Or Exit

If you are using Ubuntu with multiple users and need to switch between them, one way is to log out of your session. The fastest way to log out is to use the shortcut Ctrl+D.

Keep in mind that logging out will end any sessions and applications you are using. If you don’t want to lose what you are working on, switch users without logging out.

Click on the system menu on the top bar and select the name of the user. Or, you can create a custom shortcut.

Folder Shortcuts

Creating a new folder is easy using the shortcut Ctrl+Shift.

To see the properties of any of your folders, select the folder, and use the shortcut Alt+Enter.

If you want to rename a folder, select it, press f2, then type in the new name you wish to use.

Switch Applications

When running more than one application at a time, to switch between them use the shortcut key combination Alt+Tab or Super+Tab.

Hold the Super key and keep pressing the Tab key until you find the application you want to use. Release both keys when you find it.

The application switcher default is to move from left to right. If you prefer to move the applications from right to left, use the shortcut Super+Shift+Tab. 

The Alt key can be used instead of the Super key to perform the same task.

Notification Tray

Linux distributions like GNOME have a notification tray for various activities and systems. This is also where your system calendar is located.

Use the keyboard shortcut Super+M to open the notification area.

Use the same keys to close the tray.

Run a Quick Command

For those Ubuntu users who don’t want to open a terminal, use Alt+F2 instead to run a quick command.

If you are using applications that can only be run from terminal, this is especially helpful.

Using Ubuntu keyboard shortcuts can increase productivity and boost efficiency. Knowing which combinations of keystrokes will trigger the actions you want to perform will save you a lot of time.
