Comment(by garycmartin):

 Just tested in Safari, Firefox, and Chrome, they all use the esc key to
 stop a page load so seems an OK additional keybinding to add to Browse.
 The only potential conflict in Sugar is that esc is used to exit from
 fullscreen mode in Activities that support it (e.g. Turtle Art, Image
 Viewer). If Browse adds a fullscreen feature as some point in the future,
 esc would need some extra logic. Something like 1) if in fullscreen mode
 and a page is not loading, exit fullscreen mode; 2) if in fullscreen mode
 and a page is loading, stop loading -- this is how Safari handles the esc
 case.
