TrackPoint Middle button behavior for SketchUp

Question

When using a wheel mouse with SketchUp, pressing the wheel allows to orbit the drawing. But when I use the trackpoint, pressing the middle button zooms in/out. How can I change the behavior to be like a wheel mouse? I tried changing TP4table.dat, adding the line *,*,SketchUp.exe,*,*,*,WheelStd,0,9 in the 'Pass 0 rules' section, and restarting SynTPEnh, but this didn't cause a change. I also have a ThinkPad USB keyboard with trackpoint. The driver files seem to be under "C:\Program Files\Lenovo\ThinkPad USB Keyboard with TrackPoint", but I can't find TP4table.dat there, so what is the solution for this?

Hi,I just downloaded SketchUp and tried to simulate the behavior.What you see is the normal mouse-wheel function, scrooling up and down. What you want is the middle-click behaviour, orbiting around.I've played around with the tp4table.dat and unfortunately there doesn't seem to be a "disable scrolling but use middle-click" function.The nearest would be*,*,SketchUp.exe,*,*,*,None,0,25but this will disable zooming and orbiting (so no function at all).The 25 is the old flag 9 (3 button trackpoint, and exit function after match) + flag 16 (applying to ibm stick scrolling).Perhaps if Synaptics is asked very polite, they might add a "Middle" or "Button" option. But I wouldn't wait for it, since some other annoying bugs hasn't been solved for years. If you don't want to use the scrolling-function at all, you can switch to middle-click function inside the mouse-driver panel. A workaround would be a middle-mouse simulation hotkey. TPMiddle only supports middle-clicks, not middle drag-drops
