Nice to have all the world's alphabets at one's fingertips right there on the (www.mediawiki.org) edit page. Wow, IPA, Pīnyīn, they're all there. I'm saving it for even when I'm not editing MediaWiki.
(However, as it bloats the edit page up to 700% $ wget -O x.html http://www.mediawiki.org/w/index.php?title=WHATEVER%5C&action=edit $ perl -nwle 'print unless /onclick/' x.html|wc -c - x.html|sed '$d' 19748 - 139708 x.html there should also be some mechanism available for pages like these for users to opt out, perhaps via Preferences?)
