(Apple)对于希望提高生产力和效率的用户来说，Apple是首选，这是有充分理由的。毕竟，macOS 配备了许多让工作更轻松的键盘快捷键。将这些Mac OS X键盘快捷键与 macOS 的其他生产力功能相(Mac OS X)结合(Combine)，您很快就能比以往使用鼠标更快地导航系统。
然而，有太多的捷径，以至于很难弄清楚哪些是最有效的。以下八个键盘快捷键是用户可用的一些最有用的快捷键，也是一个很好的起点。
这些快捷键适用于所有键盘布局，但它们的预期效率是围绕使用QWERTY键盘而设计的。DVORAK和其他样式的用户可能不会觉得这些快捷方式很有用，但您仍应牢记它们。
Spotlight Search (Command + Space)
在快速搜索整个Mac以查找特定文件（甚至是来自 Internet 的信息）时，没有什么比Spotlight更好的了。即使查找快速定义也很棒。
您可以通过单击菜单栏右上角的放大镜图标手动拉起Spotlight ，但更快的选择是先按(Spotlight)Command然后按Space Bar。这样做将打开Spotlight并允许您立即开始在搜索栏中输入内容。
Quick Save (Command + S)
没有什么比丢失数据更让用户感到恐惧了。每个人都听说过程序崩溃和整个项目丢失的恐怖故事，这一切都是因为有人忘记点击Save。
事实是，没有理由忘记保存您正在处理的任何内容。快速保存是一项非常容易执行的任务，您应该让它成为第二天性。只需同时(Just)按 Command(Command)和S 即可保存文件。第一次在新文件上使用此快捷方式时，系统会提示您命名，但之后每次都会保存您的文件。
Force Quit (Command + Option + Esc)
众所周知，Command + Q是关闭应用程序的最快方法，但有时应用程序会死机。发生这种情况时，同时点击Command、Option和Esc以强制退出程序。
这两者之间的区别在于，正常的“退出”命令将使程序有机会正确关闭其操作，而“强制(Force)退出”命令实质上会使程序崩溃并强制其关闭。只有在程序无法正常关闭时才应使用 强制退出。(Force)
Trash (Command + Delete)
如果您需要快速将文件移动到废纸篓(Trash)，您无需单击并拖动。您选择该文件（或您想要的所有文件）并点击Command + Delete。这些文件将立即移至垃圾箱(Trash)，但不会立即删除。
文件在垃圾箱(Trash)中停留很长时间，并继续占用您的内存空间。删除项目后，按Command + Shift + Delete Mac OS X键盘快捷键清空垃圾箱并释放内存。
Switch Windows (Command + Tab)
即使 macOS 能够并排放置两个窗口，仍然存在需要在窗口之间切换的情况。尽管触摸板上的滑动手势可以使这更容易，但Command + Tab可让您立即在两个最近的窗口之间移动。
只需同时点击两个键即可进行交换。如果您需要在其他窗口之间导航，请按住Command然后按Tab 键(Tab)。您可以在任何当前打开的应用程序之间导航，而无需触摸鼠标。
Cut, Copy, and Paste (Command + X or C, Command + V)
这三个键盘快捷键合二为一，但它们经常一起使用，因此并没有太大的区别。您永远不(never)应该突出显示某些内容，然后使用鼠标复制它。它浪费了很多时间，可以更好地花在其他任务上。
相反，选择您需要复制的文本，然后按Command + C将其放在剪贴板上。如果要清除该文本并将其移至其他位置，可以使用Command + X将其剪切。要粘贴，您需要做的就是将光标放在正确的位置并按Command + V。
让这几条捷径成为您的第二天性，您将比以往更快地完成工作。
Select All (Command + A)
有时您需要选择屏幕上当前的所有内容。您可能需要将完整的文档复制并粘贴到另一个文档中，或者您正在文件夹内移动文件。
无论出于何种原因，您都无需单击并拖动来选择所有内容。只需(Just)按 Command(Command) + A 即可选择并突出显示当前空间内的所有内容。
Undo (Command + Z)
在处理项目时很容易出错，尤其是当您正在实现其中一些键盘快捷键并且您还没有完全掌握它们时。如果您犯了错误，请不要担心 - 只需按Command + Z即可撤消您执行的最后一个操作。
如果您不小心删除了某些内容（例如使用“全选”快捷方式删除整个文档），这将是救命稻草。您可以重复使用此Mac OS X键盘快捷方式在应用程序允许的情况下撤消之前的操作。
8 Useful OS X Keyboard Shortcuts
Αpple is the go-to choice for users who want to be more productive and more efficient, and for good reason. After all, macOS iѕ equipped with a lot of keyboard shоrtcuts thаt make working easier. Combine those Mac OS X keyboard shortcuts with the rest of macOS’ productivity features and you will soon be able to navigate your system faster than yoυ ever could with a mouse.
However, there are so many shortcuts that it can be hard to figure out which ones are the most effective. The following eight keyboard shortcuts are some of the most useful ones available to users and a great place to start from.
These shortcuts work with all keyboard layouts, but their intended efficiency was designed around use with the QWERTY keyboard. Users of DVORAK and other styles may not find these shortcuts quite as useful, but you should still keep them in mind.
Spotlight Search (Command + Space)
When it comes to rapidly searching your entire Mac for a specific file (or even information from the internet), nothing beats Spotlight. It’s great even for looking up a quick definition.
You could pull up Spotlight manually by clicking the magnifying glass icon in the top-right corner of your menu bar, but the faster option is to first hit Command followed by the Space Bar. Doing this will open Spotlight and allow you to immediately begin typing into the search bar.
Quick Save (Command + S)
Nothing strikes fear into the hearts of users quite like lost data. Everyone has heard horror stories of programs crashing and entire projects being lost, all because someone forgot to click Save.
The truth is, there is no reason to forget to save anything you are working on. Quick-saving is such an easy task to perform that you should make it second nature. Just hit Command and S at the same time to save the file. The first time you use this shortcut on a new file, you will be prompted to name it—but every time after that your file will be saved.
Force Quit (Command + Option + Esc)
Everyone knows that Command + Q is the fastest way to close an app, but sometimes apps freeze up. When this happens, hit Command, Option, and Esc at the same time to force quit a program.
The difference between these two is that a normal “Quit” command will give the program the chance to shut down its operations properly, while a “Force Quit” command essentially crashes the program and forces it to close. Force quitting should only be used when a program will not shut down normally.
Trash (Command + Delete)
If you need to move a file to Trash quickly, you don’t click and drag. You select that file (or all of the files you want) and hit Command + Delete. The files will be instantly moved to Trash, but won’t be deleted right away.
Files sit in Trash for a long time and continue to take up space in your memory. Once you delete an item, hit the Command + Shift + Delete Mac OS X keyboard shortcut to empty the trash and free up that memory.
Switch Windows (Command + Tab)
Even with macOS’ ability to place two windows side-by-side, there are still situations when you need to switch between windows. Although the swipe gestures on the touchpad can make this easier to do, Command + Tab allows you to move between your two most recent windows instantly.
Just tap the two keys in unison to make the swap. If you need to navigate between other windows, press and hold Command and then tab Tab. You can navigate between any currently open applications without ever touching the mouse.
Cut, Copy, and Paste (Command + X or C, Command + V)
These are three keyboard shortcuts rolled into one, but they are used together so often that it doesn’t make much of a difference. You should never highlight something and then copy it using the mouse. It wastes so much time that can be better spent on other tasks.
Instead, select the text you need to copy and then hit Command + C to put it on the clipboard. If you want to clear that text and move it elsewhere, you can cut it by using Command + X. To paste, all you need to do is position your cursor in the proper spot and hit Command + V.
Let these few shortcuts become second nature to you and you will finish work faster than ever before.
Select All (Command + A)
Sometimes you need to select everything currently on a screen. You might need to copy and paste a full document into another, or you’re moving files around inside folders.
Whatever the reason, you don’t need to click and drag to select everything. Just hit Command + A to select and highlight everything within your current space.
Undo (Command + Z)
It’s easy to make mistakes when working on a project, especially if you are implementing some of these keyboard shortcuts and you haven’t quite got the hang of them yet. If you make a mistake, don’t worry—just hit Command + Z to undo the last action you took.
It’s a lifesaver if you accidentally delete something (like your entire document by using the “Select All” shortcut.) You can repeatedly use this Mac OS X keyboard shortcuts to undo your previous actions as far back as the application allows.
