在Mac上快速查看是一种预览文件而无需完全打开它的有用方法。 在macOS Mojave及更高版本中，您可以在“快速查找”弹出窗口中对文件执行快速编辑，而无需打开第三方应用程序。
如何编辑和标记图像和PDF (How to Edit and Mark Up Images and PDFs)
All of Preview’s editing and markup features are now available directly in the Quick Look menu. This means you can crop an image, rotate it, mark it up with text, and even add a signature, all without opening the image in Preview. The same goes for PDFs.
现在，可以直接在“快速查看”菜单中直接使用预览的所有编辑和标记功能。 这意味着您可以裁剪图像，旋转图像，用文本标记图像甚至添加签名，而无需在预览中打开图像。 PDF也是如此 。
Start by opening the Finder app (file explorer) and locating the image or PDF. If it’s on your Desktop, click it to select it. After selecting the image or PDF, press the Space bar to open it in Quick Look.
首先打开Finder应用程序(文件浏览器)并找到图像或PDF。 如果它在您的桌面上，请单击它以将其选中。 选择图像或PDF后，按空格键可在“快速查找”中将其打开。
The Quick Look window will open up above everything. You can press the “Esc” key to go back if you select the wrong item or you no longer want to edit it.
快速查看窗口将在所有内容上方打开。 如果您选择了错误的项目或不再想要编辑它，则可以按“ Esc”键返回。
You’ll see two buttons next to the “Open with Preview” button. The first button is a quick shortcut to the “Rotate” feature. Click on it and the photo will rotate by 90 degrees (in the left direction) instantly. This is an incredibly quick way to fix a picture with the wrong orientation.
您会在“预览打开”按钮旁边看到两个按钮。 第一个按钮是“旋转”功能的快速快捷方式。 单击它，照片将立即旋转90度(向左)。 这是一种以错误的方向修复图片的快速方法。
Next to it, you’ll see the “Markup” button. Click on it, and you’ll see a new toolbar appear at the top. If you’ve used the Preview app before, you’ll recognize the editing options.
在它旁边，您将看到“标记”按钮。 单击它，您会看到一个新的工具栏出现在顶部。 如果您以前使用过“预览”应用程序，则可以识别编辑选项。
From the left, you’ll find the Sketch, Draw, Shapes, Text, Highlight, Sign, Shape Style, Border Color, Fill Color, Text Style, Rotate Right, Rotate Left, and Crop buttons.
从左侧开始，您将找到“草图”，“绘制”，“形状”，“文本”，“突出显示”，“符号”，“形状样式”，“边框颜色”，“填充颜色”，“文本样式”，“向右旋转”，“向左旋转”和“裁剪”按钮。
If you want to crop a photo, click on the “Crop” button and then use the handles to reduce the size of the picture. To insert a signature in a PDF document, click on the “Sign” button, and then select your saved signature.
如果要裁剪照片，请单击“裁剪”按钮，然后使用手柄减小图片尺寸。 要在PDF文档中插入签名，请单击“签名”按钮，然后选择保存的签名。
To add arrows or a box, click on the “Shapes” button and select a shape from the drop-down menu. You can then click on “Shape Style” to make it thinner or thicker. Click on “Border Color” button to change the color of the shape.
要添加箭头或框，请单击“形状”按钮，然后从下拉菜单中选择形状。 然后，您可以单击“形状样式”以使其更薄或更厚。 单击“边框颜色”按钮以更改形状的颜色。
Once you’re done with your edits, click on the “Done” button.
完成编辑后，单击“完成”按钮。
All your edits will be saved to the image or the PDF. Quick Look will also close, taking you back to a Finder window or the Desktop.
您所做的所有编辑都会保存到图像或PDF中。 快速查找也会关闭，使您返回到Finder窗口或桌面。
如何修剪和旋转视频 (How to Trim and Rotate Videos)
Quick Look on macOS also integrates a Rotate and Trim feature for videos. Find a video in Finder and press the Space bar.
macOS上的“快速查看”还集成了视频的“旋转和修剪”功能。 在Finder中查找视频，然后按空格键。
You’ll see two icons in the top toolbar next to the button for opening the video in the default app. The first is a “Rotate” button that quickly rotates the video by 90 degrees (in the left direction). The second is a “Trim” button that reveals a video editing tool.
在顶部的工具栏中，您会在用于在默认应用中打开视频的按钮旁边看到两个图标。 第一个是“旋转”按钮，可将视频快速旋转90度(向左)。 第二个是“修整”按钮，用于显示视频编辑工具。
You’ll see a video timeline and a scrubber in the bottom part of the window with two yellow handles at either side of the timeline. Click and hold on the handle on the left side of the timeline and pull it to where you want to start the video.
您会在窗口的底部看到视频时间轴和洗涤器，在时间轴的两侧各有两个黄色手柄。 单击并按住时间线左侧的手柄，然后将其拉至您要开始播放视频的位置。
Do the same with the right handle for where you want to end the video. If you make a mistake and you want to go back, click on the “Revert” button.
对于要结束视频的位置，请使用正确的手柄进行相同的操作。 如果输入有误，并且想返回，请单击“还原”按钮。
Now, click on “Done.” The part of the video that’s outside of the yellow handles will be removed. The video will be trimmed to the new start and end points.
现在，单击“完成”。 视频中黄色手柄之外的部分将被删除。 视频将被修剪到新的起点和终点。
If you want to perform more specific edits, you can use the QuickTime app on your Mac.
