Hello Georg,
It sounds like you have used Key Navigation to assign control of a
front panel object (a boolean) to a keyboard key. Now you are worried
that the user will hold the key down and the change of state will not
be registered in your code. Is this correct? If so, then change the
Mechanical Action of the boolean. You can do this by right clicking
on the object and selecting Mechanical Action >> Latch when Pressed.
I hope this helps.
Regards,
Joel Andersen
