5 powertools in Preview
Open a PDF? Sure. But with Preview you can do far more, from automated slideshows to scribbling all over a document
1 Sidebar speediness
Choose View > Show Sidebar to get a pane of page thumbnails for your document. That menu also contains options to switch to a table of contents, highlights and notes, bookmarks, or even a thumbnails-only contact sheet.
2 Change your view
Preview uses a continuous scrolling view of single pages by default. If you’ve opened a comic or magazine, View > Two Pages is better suited to a wide screen. Fancy slowly reading in automated fashion? Try View > Slideshow.
3 Add highlights
For basic edits to a PDF, use the Highlight button in the toolbar. Select some text, click the button’s downward arrow, and choose a colour – or use strike through to flag something for deletion. Save the file to keep your markings.
4 Make major edits
If you’re of the opinion a PDF needs more radical alteration, you can’t directly edit it in Preview, but you can pick View > Show Markup Toolbar and use its tools to add shapes, free-form sketches, sticky notes, text boxes, and signatures.
