I have a large book split into multiple PDF files. Basically one file per chapter. Currently the navigation from one chapter to the next works by clicking on a "Next chapter" link at the bottom of the last page of the current chapter.

Most of the time I use the "page up" and "page down" buttons for scrolling within a chapter. However, to go to the next chapter I have to use the mouse and click on the link.

Is there any way to "tell" the "page down" key to open the next chapter (file) when the end of current chapter (file) is reached ? In other words, when continuously hitting page-down the next file should be opened when I reach the end of the current file.

Thanks,

Andreas
