• While we don't have custom keyboard shortcuts for Zooniverse projects, the standard shortcuts for navigating any page or application work: 
    • Tab/shift+Tab to navigate forward and backward through the page (and through forms)
    • Enter/Space to activate buttons and links
    • Cursor keys to select items from menus. 
  • A full list of keyboard support for all major web browsers is maintained by WebAIM: https://webaim.org/techniques/keyboard/#testing
