Printing out huge datasheets

[KL27x]

Yes. I am sure this is the norm, rather than the exception.  The  was for me, not towards Atmel.  Microchip has both PDF bookmarks and index.

The Atmel actually has a much more thorough table of contents than the Microchip datasheets. Microchip just lists the section name and page number. It's literally just a single page. Atmel lists (most) of the pertinent things within; but it is not nearly as comprehensive as Microchip index, nor is it in alphabetical order.
