Ctrl+Click the button but select the text in its child editable multi-line text box

Can’t read minds, don’t know any criteria you’ve yet to mention… Parhaps list the requirements.

This what? Please read the question and answer it if you need help. I still have no clue what you want from the text in the button and under what circumstances should it be selectable.

That’s literally what I’ve got. Ctrl click text or button and select some text that may not be hit-testable.
