LC's htmlText supports the name attribute, so you can use something like
this:
<a name="Some text you want to display">Link Label</a>
...and then use a mouseMove handler to display that text:
on mouseMove x, y
get the linkText of the mouseChunk
if it is not empty then
DoSomethingWith it
end if
end mouseMove
Good news about the name attribute in LC: it renders without the blue
underline, so it can be a good alternative to using a link with an href
attribute if you want embedded metadata but don't want it render with
the appearance of a link.
Bad news: the name attribute is currently exclusive of the href
attribute; you can have one or the other, but not both.
I've submitted an enhancement request to remedy that:
<<http://quality.runrev.com/show_bug.cgi?id=9347>>
In the meantime, the name attribute will probably do what you need
unless you also need that same text run to have an href property.
