This is certainly true.

While working on documentation I realized that '+' and KEY_UP, contrary
to what is documented, do different things.

'+' increases volume by 1% whereas KEY_UP increases volume by 2%.

So actually it is like:

W | +           increase volume by 1%
w | KEY_UP      increase volume by 2%
X | -           decrease volume by 1%
x | KEY_DOWN    decrease volume by 2%

Still this makes no difference with my hardware, as the granularity is >
3% (e.g. snd_mixer_selem_get_playback_volume_range gives {0, 31} or {0,
15} for {min, max}).

I wonder if it would be a good idea to unify it. Consequently one could
do the same for left & right levels.
