Chouffy's Notes

Lenovo X1 Carbon Gen 7

Middle mouse button for click and scroll

TPMiddle was great to do it, but is incompatible with the X1C7.

Good thing there’s W10Wheel:

  1. In the ELAN TrackPoint for Thinkpad application, choose “Middle Button Action”: Middle Click
  2. In the Windows Settings application, go to Devices → Mouse and check “Scroll inactive windows […]”
  3. Download and launch W10Wheel
  4. In the taskbar, right-click on the W10Wheels icons and set “Trigger” to “MiddleDrag”
  5. In application, disable “autoscroll”
