Found at a thrift store in almost new condition.....for US .99 cents. I like the tactile feel of it's keys, so for now I'm making it my "for daily use" keyboard. It has 5 internet (browser) buttons (back, forward, stop, reload and home), all of which work, and three more buttons for "email", "computer" and "calculator".
Pressing the email button launches Thunderbird, neato. The computer and calculator buttons don't launch anything, but I suppose if configured, would launch apps like Thunar and gcalctool or gaclulator respectively. I don't particularly care that these two don't launch anything as I normally use the command line for file management and rarely bring up a calculator app.
Of more interest is the set of media keys/knob, with mute, stop, back (previous), forward (next}, play/pause, music (to launch a music player app) and a volume control knob. My query at the moment concerns the volume control knob. It works, but in somewhat course increments.
With the moc (Music On Console) UI up, which displays the "Master" audio control in both a horizontal bar graph and in percent (0-100) in text, I can see that the volume knob on the keyboard increases/decreases the Master volume control in even 10% steps per "click".
In W7, the volume knob is much more linear. I would like to figure out what and where I might change to make the volume control knob work in something more like 2% increments per click in F16, but I'm stumped. From
this link I was able to determine the keyboard volume knob is input "event4"...

...and poking around in /sys/class/input/input4/ doesn't reveal any possible candidates, though, and just a wild guess, the values stored in /sys/class/input/event4/device/capabilities/abs (100000000) and /sys/class/input/event4/device/capabilities/msc (10), might (?) have some relationship to the "10%" volume increase/decrease steps. In any event, as read only values, I failed to changed the values, as root, to test it.
So my question is, does anyone have any suggestions how to go about this? Priority level of this for me isn't very high, as the knob does work as is, and I have plenty of other options to set the volume level "just so", but that knob sure is handy.

Cripes! All I had to do was look at the Xfce keyboard shortcuts settings and there it was, using the amixer commands to raise/lower Master volume control in 10% increments. Edited those down to 2% and now I'm a happy camper.
Sometimes, you "look too hard" for a solution, which, in this case, is what I did, instead of checking the obvious options first. Shame on me.
