Saving to Google Drive from Google Mail

Often I get emails that are really documents; eg, travel reservations, receipts, minutes... There is a way to save them to your Google Drive as a PDF file with two clicks.  You can google "save gmail to google drive" and get many hits; one is http://lifehacker.com/quickly-save-an-email-to-google-drive-with-google-cloud-1593199317  The summary is:

1. Click the little print icon at the top of your gmail email.  
2. You will get a Print dialog page.  If the Destination field doesn't say "Save to Google Drive", click the change button under that.  Find the entry "Save to Google Drive" and click it.  If you don't see it in the selection list, click "More" at the bottom of the list.
3. Back at the Print dialog page, click Print.  Off it goes as a PDF to your drive

Note that it saves the document to the "root" of the drive.  If you want to save it in a Drive folder, you'll have to switch over to the drive, click "recent documents", and then click on the drive folder navigator to find the folder where you want to save the document.  Use your mouse to drag the document to the folder.  That's it.
