I have a faced a similar problem in some code I have written. I'm
not sure if my solution is applicable to your needs, but consider:
1. Store the buffer range of the characters you want to "HyperText"
in some suitable object. This object also contains the function
to call in response to the click. Store a list of this objects
in a slot called 'hypertext-stuff *fred-window* - *hyper-fred-window*.
(OK, don't call it 'hypertext-stuff.... call it whatever you want!)
2. When the user clicks in the window, use the fred window
function 'window-point-position to determine which buffer
character the user clicked on.
3. Search through the slot 'hypertext-stuff until the character
clicked on is in one of the ranges. Then call the function
associated with that object.
Note that by making the desired range a list of ranges [ something
like '((1 4) (12 19) (23 34)) ] and then searching for any character
in that list your "HyperText" can be discontiguos.
