[PLUG] Configuring Kensington Orbit Scroll Ring Trackball buttons

[Rich Shepard]

I've discovered there is no working 'middle' button to paste highlighted text
with my new Kensington Orbit trackball with scroll ring. The left button
highlights text and the ring scrolls scrollable pages up and down. I've no
idea what the right button does as I've not tried using it. But, when I
highlight text with the left button I cannot paste it to another virtual
terminal or application. Pressing both left and right buttons does nothing.

The software disk that came with the unit is for only Windoze and Macs.

Searching the web for button controls (to be entered in
/usr/share/X11/xorg.conf.d/10-evdev.conf) finds nothing but copies of the
one-page 'users manual' and vendors selling the item.

I found a web page on setting button mappings for the Kensington Slimblade
(for Ubuntu, but it's the same config file on Slackware) and would like to
find Orbit Scroll Ring button mappings I can put in 10-evdev.conf so I can
make the left-right button chord be the middle button that pastes
highlighted text. I find information on the company's Slimblade and Expert
Mouse but not on the Orbit w/scroll ring.

Help appreciated,

Rich
