usable tackaball

got a logitec usb trackman from ergo last week. really liked the middle style trackball, but missed scroll. the solution:

wrotenote-lx$ cat logitec_usb_trackball.sh 
#!/bin/sh
#                                              1 2 3 4 5 6 7 8 9
#xinput set-button-map "Logitech USB Trackball" 8 9 2 4 5 6 7 1 3
xinput set-button-map "Logitech USB Trackball" 1 9 2 4 5 6 7 1 3
#                                             LF  rt        lf RT
# LF = big left button
# RT = big right button
# lf = small left button
# rt = small right button

# liga emulacao do whell por movimento do mouse
xinput set-int-prop "Logitech USB Trackball" "Evdev Wheel Emulation" 8 1
# diz q par de botoes o movimento no eixo X "clica"
#xinput set-int-prop "Logitech USB Trackball" "Evdev Wheel Emulation X Axis" 8 6
xinput set-int-prop "Logitech USB Trackball" "Evdev Wheel Emulation Axes" 4 5 6 7

# apertar o botao 1 ativa emulacao acima
xinput set-int-prop "Logitech USB Trackball" "Evdev Wheel Emulation Button" 8 1

the buttons now do:

• Big left button:
  
  
  • click for Button 1 (left click)
    
  • Hold for scroll on the trackball moviment (all four directions)
  
  
• small left button: always button 1 (so i can drag things and select text)
  
• small right button: Button 3 (right click) my least used button
  
• Big Right button: middle click. I used that button a lot, to paste and thown windows to the bottom of my desktop zindex.
