The second-generation Apple Pencil magnetically snaps to the latest iPad Pro. But you might have missed a hidden button at the flat side of your Apple Pencil. Here’s how to customize the double-tap action on your Apple Pencil.
第二代Apple Pencil可以磁性吸附到最新的iPad Pro上 。 但是您可能已经错过了Apple Pencil平板侧面的隐藏按钮。 这是在Apple Pencil上自定义双击动作的方法。
The action button on the Apple Pencil is so hidden, it’s quite possible to entirely miss it or to discover it accidentally. Hold your Apple Pencil so that your index finger rests naturally on the flat side.
Apple Pencil上的操作按钮是如此隐藏，很可能会完全错过它或意外发现它。 握住Apple Pencil，使食指自然放在平坦的一侧。
Now just double-tap the flat side of the Apple Pencil. The entire bottom third of the Apple Pencil serves as an action button, so you won’t have to adjust your grip to use the feature.
现在，只需双击Apple Pencil的扁平面。 Apple Pencil的整个底部三分之一都用作操作按钮，因此您无需调整握柄即可使用该功能。
By default, double-tapping the action button will switch between the current tool and the eraser. But it’s possible to change the shortcut to switch to the last used tool or show the color palette.
默认情况下，双击操作按钮将在当前工具和橡皮擦之间切换。 但是可以更改快捷方式以切换到上次使用的工具或显示调色板。
Some pro apps even have options that will let you override the defaults for the specific app (more on that later).
某些专业版应用程序甚至提供了一些选项，使您可以覆盖特定应用程序的默认设置(稍后会详细介绍)。
如何更改Apple Pencil for iPad Pro的双击动作 (How to Change Double-Tap Action for Apple Pencil for iPad Pro)
To change the double-tap action, open the “Settings” app on your iPad Pro. If you can’t find it on your device’s home screen, use Apple’s built-in Spotlight Search feature.
要更改双击动作，请在iPad Pro上打开“设置”应用。 如果在设备的主屏幕上找不到它，请使用Apple内置的Spotlight搜索功能。
As long as your Apple Pencil is paired and connected to your iPad Pro, you’ll see an “Apple Pencil” section in the sidebar of the Settings app. Tap it.
只要您将Apple Pencil配对并连接到iPad Pro，您就会在“设置”应用的侧栏中看到“ Apple Pencil”部分。 点一下
Now, you’ll see a “Double-Tap” section. From here, switch to either the “Switch Between Current Tool and Last Used” option or the “Show Color Palette” option.
现在，您将看到“双击”部分。 从这里，切换到“在当前工具和上次使用之间切换”选项或“显示调色板”选项。
If you find the double-tap action button too annoying, or if it gets in the way of your writing or drawing, you can turn it off by tapping the “Off” button.
如果您发现双击操作按钮太烦人，或者妨碍了您的书写或绘画，则可以通过点击“关闭”按钮将其关闭。
For frequent Apple Pencil users, it’s worth switching to the last used double-tap action. When you’re using an app for highlighting or drawing, you’re usually switching between two tools.
对于经常使用Apple Pencil的用户，值得切换到上次使用的两次轻按操作。 当您使用应用程序突出显示或绘图时，通常会在两种工具之间切换。
Once this feature is enabled, open one of your frequently used Apple Pencil apps and then select one of your frequently used tools (like the pen tool).
启用此功能后，打开一个常用的Apple Pencil应用程序，然后选择一个常用的工具(如钢笔工具)。
Next, select another tool you use often (like the fill color tool). You can now just double-tap the action button to switch between the two tools, without ever touching the iPad’s screen!
接下来，选择另一个经常使用的工具(例如填充颜色工具)。 现在，您只需轻按两次操作按钮即可在两个工具之间切换，而无需触摸iPad的屏幕！
探索Pro Apps中的双击选项 (Explore the Double-Tap Option in Pro Apps)
Apple has opened up the double-tap action feature to third-party developers. Some apps will directly use your preference from the Settings app. So once you switch to the last-used option, it will carry on in third-party apps as well.
苹果已经向第三方开发人员开放了双击操作功能。 有些应用程序将直接在“设置”应用程序中使用您的首选项。 因此，一旦您切换到上次使用的选项，它也会在第三方应用程序中继续使用。
For example, PDF Expert 7 supports the double-tap actions and will throw a helpful dialog box when you first use the feature.
例如， PDF Expert 7支持双击操作，并且在您首次使用该功能时将抛出一个有用的对话框。
On the other hand, some apps let you associate specialized features to the double-tap actions that only work in the given app.
另一方面，某些应用程序可让您将专门功能与仅在给定应用程序中有效的双击操作相关联。
For instance, LiquidText lets you turn the double-tap action into an Undo button, which can be really handy when you’re annotating and taking notes in the app.
例如， LiquidText允许您将双击动作变成“撤消”按钮，当您在应用程序中进行注释和记笔记时，该按钮非常方便。
The way that Apple has implemented this hidden feature means it’s not quite coherent. You should spend some time exploring the settings in the apps where you use Apple Pencil. You might find a really useful or time-saving shortcut for the double-tap action.
苹果实施此隐藏功能的方式意味着它不够协调。 您应该花一些时间探索使用Apple Pencil的应用程序中的设置。 您可能会发现双击操作确实有用或省时的快捷方式。
Now that you’ve learned how to make your Apple Pencil more useful, you can kick things up a notch using Sidecar. Sidecar is a new feature in macOS Catalina and iPadOS 13 that lets you connect your iPad Pro to your Mac.
既然您已经了解了如何使Apple Pencil更加有用，那么您可以使用Sidecar将事情提高一个档次。 Sidecar是macOS Catalina和iPadOS 13中的一项新功能，可让您将iPad Pro连接到Mac。
Once connected, you can view your Mac’s screen on your iPad Pro, and you can use your Apple Pencil to draw directly in Mac apps.
连接后，您可以在iPad Pro上查看Mac的屏幕，并且可以使用Apple Pencil直接在Mac应用程序中绘图。
