What should happen , though? It is not a dialog, so cannot be dismissed with enter. (If it were, Esc would presumably revert changes.) If you’re working in there changing numbers and Enter moved your focus out of the panel , I daresay you’d be asking for our heads. Tab works to change fields. What looks wrong to me, and different in various pages of Properties, is that Enter does not select the value, meaning you cannot type again to correct an error, new typing is appended. That seems dumb to me.
