Hi Gene,
Re the play cut preview command, which has the keystroke C. It isn't on the
transport menu, and probably should be, so that people can find it without
having to read the manual. In the preferences dialog, under the playback
category you can set both the time before and after the selection that is
played for the play cut preview command. So if you wanted to hear a few seconds
after the end selection point, you could set the preview before cut region to
0, and the preview after cut region to a few seconds.
Re moving the the start and end of selection by tiny increments. You're right -
as the length of recording increases, the increments of the keystrokes also
increase. Sighted users can get round this by using the zoom in audacity which
reduces the increments. Users of screen readers could use the zoom, but it's
far from ideal as they obviously get no visual feedback on the degree of zoom.
However, the selection start and selection end/length controls on the selection
bar provide a very good alternative. These are slightly more complex to use,
but provide a large amount of control over how much the selection start and end
points are moved by. These controls are described in detail in the selection
bar section of the jaws guide to audacity 1.3.13, but the following is a brief
summary.
1. If the current focus is the tracks, then you can get to the selection bar by
pressing ctrl+f6, and when you want to return to the tracks press ctrl+f6 twice.
2. You can move around the controls on the selection bar by pressing tab.
3. There's a start selection control and selection control for either the end
or the length of the selection depending on the setting of the pair of
end/length radio buttons.
4. You'll want to have the format of the selection controls set to the hh:mm:ss
+ milliseconds format, and you can set this by using the context menu of either
the start selection or the end/length selection controls. Once this has be set,
the setting will remain that unless you change it again, so you'll probably
only have to do this once.
5. Set the end/length radio buttons to end, because you want to adjust
the start and end of the selection independently. (If it's set to length, then
if you change the selection start, then the end will move, because the length
has remained unchanged).
6. You can now make ajustments using the selection start and selection end
controls. So for example if you're in the selection start control. You can
quickly move to the tenths of seconds digit by pressing end, and then left
arrrow twice. You can then use up and down arrows to move the selection start
tenths of a second to the right or left respectively. Want to move by larger
increments? Simply press left arrow to move to the seconds digit, and use up
and down arrows again. Similarly, to move by smaller increments, move to the
hundredths of seconds digit. While the focus is in one of these controls you
can use all the normal playback commands to listen to your changes.
thanks for your feedback,
David.

I think we are having a miscommunication. I don't want to save a file
with labels to mark places for future work. I want to be able to record
something, edit it, and save the final version. for example, I may want
to remove commercials from a radio broadcast.
All of the movement and selection commands you described will work without
the use of labels but there is no way to move by the tiny increments I
wish to move by. the control left and right arrow and control shift left
and right arrow commands move by perhaps seven seconds, as a rough guess.
that makes doing precise editing cumbersome. The c command you discuss
provides a preview of what an edit will sound like and is useful. I
didn't know about that command before. But it doesn't provide the
intuitive means of working with the material as what I described in
earlier messages does, that is, the ability to issue a command to hear the
file play from exactly where the left selection point is and play a few
seconds farther into the file and to be able to do the same thing where I
set the end selection point.
