// @author         Mark Husson
// @namespace      http://michaelhusson.com/mark/greasemonkey/
// @description    Adds keyboard shortcuts for paging through Flickr (see notes for shortcut keys)
// @include        http://flickr.com*
// @include        http://www.flickr.com*

// How to Use:
// If you are on any page in flickr that has paging at the bottom, 
// use these keyboard shortcuts to navigate: (mac users: use cmd instead of alt)
//
// alt+n - Next Page
// alt+p - Previous Page
// alt+< - First Page
// alt+> - Last Page

// Notes:
// v0.1: Adds accesskeys to the built in paging links on any flickr page.
//       Any ideas for other keyboard shortcuts welcome
