The Quick Look tool on Macs is getting more powerful with macOS Mojave. You can now sign PDFs, trim videos, and perform other edits right from the preview pane that appears when you press Space.

To use this feature, you’ll just have to press the Space bar button with a file selected in Finder to open Quick Look, like normal. You’ll see a new action icon on the toolbar. Click it and you’ll see actions you can take to edit the current document.

For example, when working with a PDF document, you’ll see Preview’s PDF markup tools. You can draw, write, and insert your signature anywhere. When working with a video, you’ll see QuickTime editing actions like a video cropping tool. You can quickly crop a video and get just the bits you want without firing up a more powerful tool.
