Could someone give me a hint how I could find text in a (certain)
textfield in a StackMorph with a scriptable Button?

I want to build a CRC card stack where it should be possible to jump to
the collaborators. Even better than a button would be the possibility to
click on a classname in a textfield but I'm already stuck with the
scriptable button. I can't even recreate the functionality of the "back"
button with a scriptable one.
