I would like to highlight certain identifiers (such as all uses
of a particular local variable in a function) simultaneously
when the mouse enters any of them.
I've scoured the documentation, and I don't see a way to
accomplish this feat.
Would it be reasonable to add mouse-entered and mouse-left
properties analogous to point-entered and point-left?
Alternately (or in addition), it might be nice to have text
properties analogous to the mouseenter, mouseleave and
possibly mouseover standard browser events, which would
fire at the granularity of pixels rather than characters.
Maybe I'm misunderstanding, but if you mean highlight the text whenever the
mouse is over it, you can do that using text property `mouse-face'. (That has
character granularity however.)
To have the mouseover highlight appear for certain words etc., you would need to
apply property `mouse-face' to those words.
AFAIK, font-lock cannot be used for this, since it always uses the `face' text
property. (But maybe I'm wrong about that.) It might be an interesting feature
for font-lock to let you specify a different text property to use.
