A translator friend asked me to do this so that he could look up words and references rapidly, without having to go to loads of bookmarks or Google. It occurred to me it could be useful to authors and editors.
You just select a word or phrase and then press a windows shortcut, and it searches whatever resources you have preselected (e.g. Wiktionary, Webster online, Cambridge online, etc)
You can create your own groups of resources and associate them with specific shortcut keys.
The alpha version only works with the "windows" metakey.

There are instructions inside the Zip.
It is based on AutoHotKey, which you will also have to download. I would hugely appreciate any feedback of any kind, but especially, your suggestions of resources to add to the (very small) selection currently available. I can add new ones very quickly; all you have to do then is download a new definitions file.
