I'd like to switch the accessibility preference "Scroll with inertia" on and off for a Magic trackpad. The preference can be found in the accessibility preferences/Mouse and Trackpad/Trackpad Options/Scrolling "with/without inertia" (see here: http://de.tinypic.com/view.php?pic=2rw00wg&s=6#.U_NrJrx_ulA).
I think, that this preference resembles the key "TrackpadMomentumScroll" in either the com.apple.AppleMultitouchTrackpad or com.apple.driver.AppleBluetoothMultitouch.trackpad domain.
Using the defaults command doesn't seem to change the preference. At least, OS X doesn't react to the command and the preference in the GUI isn't reacting either.
I guess, I need to restart some daemon to apply the change.
Can somebody help me here?
Kind regards Dennis
