Yes, it can. The text you add in the "Title" field shows up in a tooltip when you hover over the keyword.
I see that field, but just to make sure:
- is there any plan to make it as a rich field? with a rich editor? (because the definition we add for each word, is usually a few lines with links and it happens sometimes to include media, either embed or attached)
- if the answer to #1 is yes, do you plan to add support of attachment handler to it as well?
To help clarify the exact usage, let me bring a real example from our site: it's a legal social network. a lot of special legal phrases/statements are used all around the site. a lot of them are very hard to understand (not just to public, but even for law students in first years) so we want to provide the tools to help viewers get the best out of the content in the site (so in some words, we define and explain the word, we bring examples from law, and if there are any media or article in our site about it, we link to them, and if any attachment would come handy, we would provide them)
I know it may be too much for the Title field in Keyword ad type, but could be a handy tool which opens new usage ideas of that ad type too.
(btw, back in Glossary time, it had a page where all the phrases where there in different categories. So the categories were Dictionaries ,and each dictionary had sub-categories which were alphabet characters, and each of them contain phrases. when you were inside a phrase, you could see the title, definitions, attachments, synonyms, antonyms related phrases, which all were defined by us, plus the comments section where users could discuss around that word, and all other content of it. and when a word was linked around the site, in the tooltip that contained the definition, there was a link to phrase page as well, for more info and discuss.)
