The nyquist sliders can presumably in near future better represent the
actual values, once the expanded WXWidget functionality is
implemented.
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 %
However, this needs 6 additional key assignments and one never knows
what the actual setting is, you have to open the dialog to see it.
In general, it wouldn't be a problem for any screen reader to announce
the slider value while pressing the arrow keys (depends on the effect
type).
