Since I've been programming in X and reading this newsgroup for a couple of years, I'm probably not alone. Could someone higher on the hipness scale drag an introduction to this over here and drop it into the flow?

You can see "drag & drop" in action by looking at a Mac user copy files. 1) select desired file(s) 2) click and hold the mouse button 3) DRAG the selected files to the desired location 4) DROP the selected files into the directory by releasing the mouse button Or, watch someone use the Sun OpenWindows file manager tool, which does the same thing. Sun's mailtool for OpenWindows (and probably most other Sun OW tools) provide D&D for text editing also: 1) hilite the text to copy 2) click & hold left mouse button (first 7 letters shown in a little box) 3) DRAG to new position in text flow 4) DROP the copy into text flow by releasing the mouse button The concept also comes under the heading of "direct manipulation" in human factors/CHI texts.

You can also load a file into application by dragging its icon from the File Manager's window into the application's window or icon. The current Sun's interpretation of D&D is incomplete, at least as far as OW 2.0 is concerned. First, it allows D&D copying only between two XView or two OLIT windows. Second, it still waiting for a reasonable interpretation of D&D of an icon residing on a remote server. A more "mature" implementation is in the works, as I understand.
