I write an astrology blog and some friends suggested I put in a dictionary to define some of the technical terms.
What I think would be great is if I had a dictionary, or text file with a word and definition. If one of the words in the dictionary I create is in an article I write, then the word is distinguished (by color or decoration) and the user can then hover the mouse over the word to get the tool tip (basically the title tag of the anchor).
Does that exist? How hard would it be to create?
