If you use Apple Mail, you may have noticed you can swipe messages to perform certain actions. It’s a useful shortcut, but if you find yourself invoking it accidentally, here’s how to turn this feature off.
如果您使用Apple Mail，您可能已经注意到可以滑动邮件来执行某些操作。 这是一个有用的快捷方式，但是如果您发现自己不小心调用了它，可以使用以下方法关闭此功能。
We’re not strangers to configuring Apple Mail to better suit our purposes. We’ve talked about how to create and modify signatures and append them to the end of your e-mails, how to turn off event and contact suggestions, and even shown you ways to better manage your inbox with rules.
我们对配置Apple Mail使其更适合我们的目标并不陌生。 我们讨论了如何创建和修改签名并将其附加到电子邮件的末尾，如何关闭事件和联系建议 ，甚至还向您展示了使用规则更好地管理收件箱的方法。

But message swiping might be one of those features you might have thought you were stuck with because there’s no obvious way to turn it off, let alone change what it does.
但是消息轻扫可能是您可能以为自己被困住的那些功能之一，因为没有明显的方法可以将其关闭，更不用说更改其功能了。
Message swiping works exactly like it sounds. If you want to delete a message, you can swipe left on your trackpad.
邮件滑动的工作方式与听起来完全一样。 如果要删除消息，可以在触控板上向左滑动。
If you want to mark a message as unread, you simply swipe right.
如果要将邮件标记为未读，只需向右滑动即可。
This may appeal to many users, but others may miss the older, “classic” layout that Apple Mail used to sport. Or maybe you don’t have a trackpad, and swiping is impractical. No worries, it’s quite easy to enable the old interface and disable message swiping in the process.
这可能吸引了许多用户，但其他人可能会错过Apple Mail以前使用的较旧的“经典”布局。 或者，也许您没有触控板，并且刷卡是不切实际的。 不用担心，启用旧界面并在此过程中禁用消息轻扫非常容易。
Start by opening Apple Mail’s preferences by clicking on the Mail menu and clicking “Preferences” or pressing Command+, on your keyboard.
首先通过单击邮件菜单上的Apple偏好设置，然后单击键盘上的“偏好设置”或按Command +。
With the Preferences open, click the Viewing tab and note the section at the very top that says “Use classic layout”.
在“首选项”打开的情况下，单击“查看”选项卡，并注意最上方的“使用经典版式”部分。
When you check this box, you see your Mail inbox is transformed to Apple Mail’s so-called classic look.
选中此框时，您会看到您的邮件收件箱已转换为Apple Mail的所谓经典外观。
Now, instead of swiping to affect message as we described earlier, you can use the right-click context menu.
现在，您可以使用右键单击上下文菜单，而不是像我们之前描述的那样滑动以影响消息。
Another option is to customize the toolbar, adding the the unread/read buttons and any others you deem necessary.
另一种选择是自定义工具栏，添加未读/已读按钮以及您认为必要的其他任何按钮。
To do this, simply right-click on the toolbar and select “Customize”.
为此，只需在工具栏上单击鼠标右键，然后选择“自定义”。
Then drag whatever button or buttons you need into the position you want them.
然后将所需的任何一个或多个按钮拖到所需位置。
And, as easily as that, you have managed to disable message swiping without losing the ease of its functionality.
而且，如此轻松地，您设法禁用了消息滑动，而不会失去其功能的简便性。
Unfortunately, for anyone who does like the message swiping feature, there’s no way to change its actions. It might be nice to be able to swipe to reply or flag a message, but as of now, it’s only the two: delete and mark as unread.
不幸的是，对于喜欢邮件滑动功能的任何人，都无法更改其操作。 能够滑动以回复或标记消息可能会很好，但是到目前为止，只有两个：删除和标记为未读。
Hopefully in some future release, Apple will add more power to it, but at least in the meantime, you can disable it.
希望在将来的某些版本中，Apple可以为其增加更多功能，但是至少在此期间，您可以禁用它。
