Hi Andrew,
thanks for the feedback.
Concerning the difference in balance between forwards and backwards at low
speeds. I can't reproduce the effect. Maybe it's caused by slight
differences in the responses of the left and right driver units in your
headphones. I assume that if you reverse the audio using the reverse
effect, then that also has the same effect at slow speeds.
Concerning the using of scrubbing to precisely locate the start and end of
a time selection. Am I right in thinking you are using the split command
(ctrl+I) at either end, and then selecting the clip? An alternative, which
is what I was assuming people would use, is to make use of the store cursor
position, and cursor to stored cursor commands. You can also use the left
and right bracket keys during scrubbing, but I appreciate that many may
find it easier to set a precise time using key up rather than key down.
Concerning the shift+f5 to f8 keys. These are only defined in the full set
of default keys, and the standard set is the default. So on a fresh
installation, you have to go into keyboard preferences, and set the
defaults to the full set.
David.

Hi David
I have now had a more detailed play with scrubbing. In summary, I love
it. I had not bothered with zooming previously, but control-1, control-2
and control-3 allow effective adjustment of scrubbing speed. While I am
primarily interested in scrubbing at slow speed, there are situations where
high speed would be useful. The following is by way of interest rather
than concern. when scrubbing backwards while zoomed right in on a
recording done with a mono microphone on a stereo track, sound is stronger
through the right channel. When scrubbing forwards the sound moves to the
left channel. This does not happen at higher speeds. Again, I do not
regard it as a problem.
One of my uses of scrubbing is to locate precisely points before and after
something to be deleted. I therefore had some initial concern about
scrubbing cancelling selection. The solution is to use clips instead of
selecting. Pleasingly, keys shift-f5 through shift-f8 behave the same for
clips as for a selection. As a bytheway, those keys were not defined in
the dev version but will presumably be reinstated before release.
Once again, I regard keyboard access to scrubbing as a very significant
inclusion into Audacity. While we had some debate about using arrow keys,
I am more than comfortable with this implementation. While different to
other DAWs, I suspect most people will be able to adjust.

Hi,
there's now a version of scrubbing using the keyboard in the development
version of Audacity, if anyone wants to have a play with it. Note that this
is a development version, and it's not recommended for normal use.
There's a zip file, available here:
https://github.com/audacity/audacity/suites/409383387/artifacts/1220464
The zip file contains another zip file, which contains the portable
version of audacity. Unfortunately this double zipping happens with the
current automatic build scheme being used.
The details of the user interface are given below, and are similar to the
original proposal, with one or two minor changes. For using scrubbing to
position the cursor, you'll get the most accurate results on Windows using
the Wasapi host.
- There are two new commands: Scrub Backwards and Scrub Forwards.
- These commands appear on the Transport sub menu of the Extra menu.
- The commands have default shortcuts U and I, and are in the standard
default set.
- After pressing one of the two keys, playback continues until the key is
released.
- Playback starts from the cursor position, or the start of a time
selection if there is one.
- The speed of playback is determined by the zoom level. If the zoom level
is normal, then the playback speed is one half of the normal playback
speed. Zooming in (Ctrl + 1), halves the playback speed, and zooming out
(Ctrl + 3) doubles the playback speed. There are minimum and maximum
playback speeds of one sixteenth, and three respectively.
- You can scrub to the end of the audio, even if there is an initial
selection. In other words, scrubbing forwards does not automatically stop
at the end of the selection.
- Normally, when one of the keys is released, the position of the cursor
is set to the time when the key was released.
- If during the time one of the keys is pressed the left bracket and or
right bracket keys are pressed to set the start and/or end of the
selection, then when the scrubbing key is released, the change to the
selection made by pressing the bracket keys is preserved - the position of
the cursor is not set to the time when the key was released.
- If you hold down one of the scrubbing keys, and then press the other
scrubbing key before releasing the other key, then scrubbing continues in
the opposite direction, and does not stop when the original key is released.
David.
