Added scrolling support to MS Ergonomic Keyboard 4000
Using these trusty steps, courtesy Philipp Klaus:
sudo aptitude install xbindkeys xautomation xdotool
sudo tee /lib/udev/keymaps/microsoft-ergonomic-keyboard << EOF
0xC022D 0xC1 # Zoom In
0xC022E 0xC2 # Zoom Out
EOF
sudo sed -i \
's/0xc022d zoomin 0xc022e zoomout/microsoft-ergonomic-keyboard/' \
/lib/udev/rules.d/95-keymap.rules
cat > ~/.xbindkeysrc << EOF
## Use the slider to scroll up and down

"xdotool click 4" # Scroll Up
c:201
"xdotool click 5" # Scroll Down

Run each command, then disconnect & reconnect the keyboard, then run xbindkeys. Worked liked a charm.
