L.S., It is easy to define the search facility of the Haskell wiki as a search engine in the Opera browser. Press alt-p to get to the preferences panel (details differ per Opera version) and define the following parameters for the new search engine: Name HaskellWiki Keyword hw Address https://wiki.haskell.org/Special:Search?search=%s Now you can enter, for example, hw wxHaskell on the URL bar, to get to the wxHaskell page on the Haskell wiki. Another option is to double click a word on a web page, right click on the word and select Search with -> HaskellWiki. Similarly, you can search with Hoogle: Name Hoogle Keyword h Address http://www.stackage.org/lts-2.22/hoogle?q=%s Hackage: Name HackageDB Keyword hd Address https://hackage.haskell.org/package/%s Hayoo: Name Hayoo Keyword hay Address http://holumbus.fh-wedel.de/hayoo/hayoo.html?query=%s Regards, Henk-Jan van Tuyl -- Folding@home What if you could share your unused computer power to help find a cure?
