It is possible to select a portion of the pdf preview display and copy and paste the resulting graphic into another program. Drag and drop of the selection is also supported. Preference items allow users to select the file type of the copy (pdf, png, jpg, tiff, etc.) and the foreground and background colors and transparency.

Preview selection combined with drag and drop can be used with Keynote. Using the default copy preferences, a text selection can be dropped on a Keynote slide; the background of the text will be transparent, so the slide background will show between the letters. This text can be resized since the default copy format is pdf.

The Edit menu's "Select All" command can be used to select the entire pdf page for copying. However, in Multi-Page and Double-Multi-Page modes Select All only works if the document has 20 or fewer pages, since otherwise the selected pdf could be enormous and copying could bring the machine to a crawl.
