Four PDF Tips for Snow Leopard

Macworld recently published the following tricks that everyone should know for owrking with PDF documents in Mac OS X 10.6 (Snow Leopard):

1. E-mail PDFs with one click :: When you have a file you want to share, just press Command-P, click on the PDF button in the Print dialog box, and then choose Mail PDF. Your Mac will create the PDF, launch Mail (or your default e-mail program) if it’s not already open, and then create a new message and add the PDF as an attachment.
2. Save a page (or three) from a PDF :: First, open the PDF in Preview (in your Applications folder). Reveal the sidebar by clicking on the Sidebar button on the Preview toolbar (or by pressing Command-Shift-D). You should see a thumbnail of every page in the document. If you don’t, click on the second button from the left at the bottom of the sidebar (or press Command-Option-2). Find the page you want to save, and then drag its thumbnail from the sidebar to a Finder window or to your Desktop. If you want to drag multiple pages, select them (Shift-click to select adjacent pages, or Command-click to select non-contiguous pages) and them drag them the same way. Whatever you select and drag to the Finder will be saved as a PDF with the name PDF name(dragged).pdf.
3. Merge PDF pages :: First open one of the PDFs with Preview, and display the sidebar with thumbnails (as described above). Drag the second PDF on top of the first one. This changes the display of the first PDF in the sidebar. Click on the arrow button to “close” or “open” the PDF, toggling between showing just its first page and all the pages it contains. This makes it easy to make sure you’ve put the documents in the right order. When you press Command-S to save the document, Preview will save the whole thing within the document of the first PDF file that you opened. (Alternatively, you can save it as new document by pressing Command-Shift-S and choosing a new name.)
4. Read PDFs more easily on a laptop :: Follow these steps to read PDF files like books on a laptop. In Preview, choose Tools -> Rotate Left or Rotate Right. Now you can hold your laptop like a book (screen in one hand; keyboard in the other). Flip the laptop to choose which side you want the screen on for easy reading.  If you use Adobe’s free Adobe Reader, you can go one step further. Choose View -> Rotate View -> Clockwise (or Counterclockwise), then press Command-L to enter full-screen mode. Flip pages by pressing the spacebar, or go back a page by pressing Shift-spacebar. You can read PDFs like this without the distraction of menus and toolbars, and make the content as big as your screen can hold.
