The nyquist sliders can presumably in near future better represent the
actual values, once the expanded WXWidget functionality is

However, I don't think that the 3 sliders that David has mentioned are
the best reference:

1.  arrow key movement creates much too large steps (10 % at a time).
2. No fine tuning with modifier (shift) or up and down keys.
3. page up and down, the same (50 % at a time).

Note that the volume sliders (input/output) move one % with arrow keys
and 20 % with PgUp/PgDn.

The separate shortcuts for increasing/decreasing the respective values
are in contrast finer tuned:
Gain=1 dB (1.4 %), Pan=5 %, Play at speed=1 %

the slider value while pressing the arrow keys (depends on the effect
