The New Hotness

XFCE Keyboard Mapping: Random Jots
The multimedia keyboard on this box doesn’t work, which likely has something to do with the fact that I’m running separate X sessions on two monitors. I described what does work on my laptop there.

Here are some random & incomplete notes, with no good outcome…

Key and keyboard definitions are in /usr/share/X11/xkb/keycodes with:
- xfree86 mapping the symbolic name (as in <I1E>) to key number 158
- inet mapping from XF86AudioRaiseVolume to symbolic name
The Microsoft Comfort Curve Keyboard 2000 V1.0 (don’t you love how they name things?) seems to be a subset of the microsoftprousb keyboard definition.

Manually assigning a key works like this:
```
xfconf-query -c xfce4-keyboard-shortcuts \
  -p /commands/custom/XF85AudioRaiseVolume \
  -t string
  -n
  --set="amixer -c 0 sset Master 10%+"
```
Use xev to find key numbers, which turn out to be more or less common values (contrary to what I initially thought)…
- Back = 234 I6A
- Forward = 233 I69
- Vol down = 174 I2E
- Mute = 160 I20
- Vol up = 176 I30
- Play/Pause = 162 I22
- Home = 178 I32 XFree86HomePage
- Search = 299 I65 XFree86Search
- Email = 236 I6C XFree86Mail
- Calculator = 161 I21 XFree86Calculator
The first two keys are defined in nav_common and the rest are in media_common, with the combination in, of course, media_nav_common.

But none of this actually works.
