Want short demos of interesting Interlisp features
the Interlisp way, file package, masterscope, versioned file system, dwim, break package, lispx commands, spy
lafite, tedit, image objects, grapher
The outline of demo features in the LispNYC slide presentation corresponds to a breakdown of demos to give

There are a couple of videos demos listed in the Medley Wiki but nothing systematic.
Writing a script would be the first order.
@skaisler1 want to try your hand at script writing? I was thinking we could do a lot of short (2 minute) feature demos. I could get some help editing recorded screen-share demos, perhaps linked to chapters of the books.
The explanation of how to use the Medley mouse and keyboard probably would be best a video clip;

Interlisp Exec: You need a 2 or 3 button mouse, or know how to have your trackpad/buttons generate a right-mouse-button event as well as the left-mouse-button event. Then: right-mouse-button down (and hold) in the background (the gray stipple not in any window) and you'll get a pop-up menu with EXEC as one of the items, slide the mouse pointer over that until it highlights, then slide right (it has the ► to indicate it has sub-menus) and over the "Interlisp" item (it also has sub-menus) and release the mouse button on the highlighted "Interlisp" item. It will then prompt you to position and size the new Exec window -- left button down to freeze the top-left corner and drag out the region and then release it to set the lower-right corner. Click in the window to give it the keyboard focus and then you can type at it.
@zbraiterman ?
@masinter I'd be honored to help create a demo. Thank you for thinking of me. :)
I like the idea of "live" demos which are actually done inside medley, with image objects. The video is to show them that it's easy ad what to expect.
