[Pharo-users] Detecting keystrokes in Spec2 input fields

Hi Is there a simple way to detect when a use makes a keystroke in for example a Spec 2 Text Input Presenter? I’ve been going through all the relevant classes and methods, even into Morphic, but so far I have not found a way to do it. I want to be able to identify when unaccepted changes have been made to the displayed text to ensure that a use does not leave a form without saving any input made. Regards Robert
