If you'd bothered to read all of my original posting you'll see that that
tool is available to her, but she chooses not to use it for that specific
task.  Creating sheet music is too different from creating music. When you
create sheet music, you are interested specifically in how the symbols
look on the page.  It is much easier to directly put the symbols where you
want them than it is to play a note, and hope it goes in the rght spot.
The vertical placment is solely a function of pitch, but the horizonatal
placement is a function of the typesetting requirements of all the verses
of lyrics and also of esthetics.

The time domain data is much faster to specify with the typewriter
keyboard than it is in the time domain itself.  With the mouse and
typewriter keyboard system you can get whole notes on the page much faster
than you would play them.  (You could fix this by adding a foot pedal,
that adjusted an on-screen display of tempo.)

Note, I've directed follow ups to the user interface group.

How does one get this videotape?  Through ACM?  Anyone know the mechanics
of doing that?  I had been hunting for this book by Adele Goldberg while
also looking for the proceedings of the conference - I didn't realize they
were the same thing. 8^)  Thanks for the info; now I should be able to find
