I'm working on a FileMaker Go layout that has button bars and regular fields. Users can tab through the regular fields fine (using the tab key on their Bluetooth or iPad Pro keyboard) but the button bars are skipped. This is different behavior to the desktop version, where button bars respect the tab order. After more investigation it appears that attempting to make a button bar active by using "Go To Object" throws error 3 (Command is unavailable (for example, wrong operating system or mode)). I can't see this behavior documented anywhere. Does anyone know the types of object that can be active or in focus on each version of FileMaker?
