Many thanks for your reply.
Several WYSIWYG editors use the term "screen tips" to describe a built-in function for what you describe as the yellow MS Word-like tool tips.
Not only used for pics as an alt attribute but on top of hyperlink text for usability and accessibilty support.
If it (as you explain) does not hurt (considered spamming?) I would consider using them for exactly this reason, repeating the original link text without any keyword stuffing of course.
Switzerland for example is about to launch a new regulation where governmental web sites have to satisfy certain usability and accessibilty criteria, industries follow suit.
If this practice gets established it might be a solid habit to default on it.
