Per bug 29753 comment 17, I copy below the content of bug 29753 comment 16:
When I acess wikipedia using Mozilla/5.0 (X11; U; Linux x86_64; pt-br)
AppleWebKit/531.2+ (KHTML, like Gecko) Version/5.0 Safari/531.2+ Debian/squeeze
(2.30.6-1) Epiphany/2.30.6, MediaWiki suggests the use of "ctrl-shift-" but it
should suggest "alt-shift-".
Version: 1.19
Severity: normal
OS: Linux
