I have also found drag-and-drop to be unreliable and inneficient, even with the JAWS hot keys for this. I think the same functionality can usually be provided through well-designed wizards.

Hi Laura, It's interesting to hear that you find drag and drop easy in audio. If it works well for you, that's great. All I'm suggesting is that there may be a better way to achieve the same effect as drag and drop in audio. As far as I know (and correct me someone if I'm wrong) nobody has really looked into the alternatives. Drag and drop was "invented" for visual displays. Is there an equivalent or more powerful metaphor for audio? What if you have to go to work at a new company and are unfamiliar with where the icons are located on the desktop. The first time you use drag and drop, you have to explore their spatial relationships. But why should you need to do that? All you really want to do is be able to associate one object with another and not worry about switching cursors and moving them in certain directions. Perhaps there's a way to easy the learning. There is also room for improvement from an information theory point of view. The key presses needed to switch cursor modes and the time needed to move one object to another are not critical to the task of associating object and action. By eliminating them, or reducing the time it takes to perform them, you'd have a better interface, purely from an efficiency standpoint.
