Hello Bob and list,
thank you for your helping answers, and for further developing hyperbole! I succeeded to add ("Leo" . "http://www.dict.leo.org/frde/?search=%s") to the hyperbol-web-search-alist. either with 'push' or 'setq' (setting all web-addresses) I can now use this link with buttons, but it does not show up in the menu {C-h h f w} as a possibility to select. Could you please help me to achieve this? The examples from Jean Louis were very helpful. Perhaps it would be a good idea to add longer and more examples to the documentation of hyperbole? ---- Erich
