Structured Text - Execute Code On Pressing A Word

[Tostm8 1]

Hello,

 

So I've been making a Morrowind style dialog GUI and I've hit a snag. I'm trying to use a href link in some structured text to execute some code but I don't think it's possible. As far as I'm aware you can only put urls in there. Is there a way to be able to press a word and it would then execute some code? Other than the way I tried already.

Thanks in advance!
