Re: keys for store cursor position and cursor to stored curso.
I use these all the time and love them, especially for labeling long
ranges. Alt+s,i and Alt+s,c works great.

Hi David
Yes, I was using control-I to create a split at relevant points. Being slack, I had not assigned keys to store cursor position and cursor to stored cursor commands and therefore had not used them a great deal. I have now done that and it is a nice option. All of this makes my labelling demo rather outdated. I am thinking of redoing it once specs on scrubbing are confirmed.
Re the function keys, my bad. I have been simply updating Audacity for so long I forgot that button.

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.
