我有一台配备点击板的联想 ThinkPad Yoga。我想使用中间的点击板按钮启用滚动功能。因此，我希望能够通过按住中间按钮然后在要滚动的方向移动鼠标来滚动编辑器。我已将此点击板设置为可识别与鼠标按钮 1、2 和 3 相对应的三个软按钮。Synaptics 配置如下：
Section "InputClass"
Identifier "Default clickpad buttons"
MatchDriver "synaptics"
Option "SoftButtonAreas" "64% 0 1 42% 36% 64% 1 42%"
Option "AreaBottomEdge" "1"
EndSection
xinput 设备列表（xinput --list）如下：

如果您能提供任何有关启用中间按钮滚动的指导，我将不胜感激。谢谢！
编辑：我购买了一款外置 ThinkPad USB 键盘，它同时配有 TrackPoint 指点杆和三个专用鼠标按钮。我已使用此键盘成功执行了向上滚动和向下滚动操作，并记录了相关输出xev。
以下是xev成功向上滚动操作的输出：

那么，有了这些额外的信息，你们这些好心、聪明的人能不能指点一下如何在我的 ThinkPad 上实现这种滚动功能？:)

您是否尝试过xinput像链接中提到的那样进行设置在此主题中? 所识别的设备TPPS/2 IBM TrackPoint与那里解释的完全一致。
