   • Shift-Spacebar (page up)
   • Ctrl+F (find)
   • Alt-N (find next)
   • Ctrl+D (bookmark page)
   • Ctrl+T (new tab)
   • Ctrl+K (go to search box)
   • Ctrl+L (go to address bar)
   • Ctrl+= (increase text size)
   • Ctrl+- (decrease text size)
   • Ctrl-W (close tab)
   • F5 (reload)
   • Alt-Home (go to home page)
4. Use auto-complete in the address bar
