J602 uses wd http://www.jsoftware.com/help/user/wd_commands.htm The problem with wd and its controls is that you only can take action for the events that that control supports. Some notes I made for myself some time ago (http://www.jsoftware.com/jwiki/Raul%20Miller/J%20Event%20Handlers) suggest to me that only function keys get event handlers in an edit control. (Some controls get event handlers for all keys, but edit controls do not.) For a more versatile and generic UI design, I think you are going to need j7 (but that's still bleeding edge, so you should be prepared to spend some time isolating problems which do not exist in j602). -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
