Thanks for giving more information about what you're looking for.

However, I must admit having no experience in that. Sorry. But, if I had to
try and understand why your above code does not work, I would first give a
deep look at some agenda commands: I know they *do* use "text properties" (for
handling the clicks on the agenda line, in particular). These could help you
achieving your goal, maybe?

Best regards,

Sebastien Vauban
