Has anyone thought about adding what, for the lack of a better phrase, I will c
"real hypertext." to Hypercard or SuperCard.  By hypertext, I mean the ability
to link a span of text in a field to a command.

In Hyper/SuperCard, you can create a text field and put transparent buttons ove
the text field so when the user click on a word, a command is executed.
Unfortunately, if the text is edited, all the buttons have to be moved.  It's a
real mess if the field can scroll.

As far as I know, it is impossible to catch all the editing events that affect 
field (character insertion, cuts, pastes, etc.) or find the bounding box of a
span of text, so hypertext can not be implemented by clever scripting.

Does anyone have any illuminating thoughts?
