Hi Wolfgang I share your passion for empowering a human operator to complete and submit a form as quickly as possible. I therefore agree that one should be able to complete a form using the keyboard only. There is an aspect I am unsure of, and would appreciate any feedback based on your experience. I am talking about what I call 'field-by-field validation'. Each field could have one or more checks to ensure that the input is valid. Some can be done on the client (e.g. value must be numeric), others require a round-trip to the server (e.g. account number must exist on file). Some applications defer the server-side checks until the entire form is submitted, others perform the checks in-line. My preference is for the latter. I agree with Chris that on a LAN, it makes little or no difference whether the client side is running a web browser or a traditional gui interface. On a WAN, there could be a latency problem. Ideally an application should be capable of servicing a local client or a remote client, so it is not easy to find the right balance. Do you have strong views on which is the preferred approach. Thanks for any input. Frank Millman -- http://mail.python.org/mailman/listinfo/python-list
