// Quick Usage Instructions
// ========================
// This script provides global access to Google's experimental keyboard
// shortcut search feature on all search results. The original feature page is
// located at: http://www.google.com/experimental/
//
// In addition to the standard Google keyboard shortcuts (J,K,O,ENTER,/), this
// script also adds the 'H' and 'L' keys (lowercase) to quickly jump to the
// Previous and Next search results page.
//
// Notes For Current Users of Google Labs Experimental Search
// ==========================================================
// This script does not require you to join Google's "Experimental" search
// feature to work properly. If this feature was previously activated in your
// user account, then you should click the "Leave" option after installing the
// script. The option is located at: http://www.google.com/experimental/
