New, much simpler solution using AutoHotKey

I've been looking for a way to avoid freezes caused by constant checks for the active window and also an overall simpler code solution. Here's what I made:

#ifWinActive ahk_class Framework::CFrame
    WheelUp::
        ControlGetFocus, control, A
        Loop 3
        SendMessage, 0x115, 0, 0, %control%, A
    Return

#ifWinActive ahk_class Framework::CFrame
    WheelDown::
        ControlGetFocus, control, A
        Loop 3
        SendMessage, 0x115, 1, 0, %control%, A
    Return

Change the Loop 3 to Loop 5 or however many lines you wish for one movement of the wheel to scroll.

old solution using AutoIt

Note: this solution may cause stuttering and occasional freezes on older CPUs or at full CPU load.

我启动了一个AutoIt脚本，该脚本可检测注释列表区域内的光标，并且如果您向上或向下滚动，请在滚动条上单击“向上”和“向下”按钮。这适用于多个OneNote窗口。您无需专注于窗口即可使滚动工作，只需将鼠标悬停在该列表上即可：

#include <AutoItConstants.au3>
#include <MsgBoxConstants.au3>
#include <MouseOnEvent.au3> ; get it from https://www.autoitscript.com/forum/topic/64738-mouseonevent-udf/
#include <WinAPI.au3>
#include <Misc.au3>

_MouseSetOnEvent($MOUSE_WHEELSCROLLUP_EVENT, 'MouseWUp')
_MouseSetOnEvent($MOUSE_WHEELSCROLLDOWN_EVENT, 'MouseWDown')
Opt("WinTitleMatchMode", 2) ; 2 - substring mode

Global $clicks = 3 ; how many items to scroll per scroll, change this to 5, 8, 13, 42 or however fast you wanna scroll

Func MouseWUp($iEvent)
  If StringInStr(WinGetTitle($hWin), " - OneNote") Then

      ; check if cursor is within the notes list and not anywhere else
      Local $cur = MouseGetPos()
      Local $handle = $hWin ;WinGetHandle("[ACTIVE]")
      Local $wpos = WinGetPos($handle) ; returna array of x,y,w,h
      Local $cpos = ControlGetPos ($handle, "", "[CLASS:NetUIHWND; INSTANCE:5]")
      ;MsgBox($MB_SYSTEMMODAL, "title", "win2:" & $wpos[2] & "; win3:" & $wpos[3] & "; cp2:" & $cpos[2] & "; cp3:" & $cpos[3])

      If ($cur[0] > $wpos[0] + $wpos[2] - $cpos[2]) And ($cur[0] < $wpos[0] + $wpos[2]) Then

         Local $x = $cpos[2] - 2
         Local $y = 58
         ControlClick($handle, "", "[CLASS:NetUIHWND; INSTANCE:5]", "left", $clicks, $x, $y)

      EndIf

   EndIf
EndFunc

Func MouseWDown($iEvent)
   If StringInStr(WinGetTitle($hWin), " - OneNote") Then

      Local $cur = MouseGetPos()
      Local $handle = $hWin ;WinGetHandle("[ACTIVE]")
      Local $wpos = WinGetPos($handle)
      Local $cpos = ControlGetPos ($handle, "", "[CLASS:NetUIHWND; INSTANCE:5]")

      If ($cur[0] > $wpos[0] + $wpos[2] - $cpos[2]) And ($cur[0] < $wpos[0] + $wpos[2]) Then

         Local $x = $cpos[2] - 2
         Local $y = $cpos[3] - 8
         ControlClick($handle, "", "[CLASS:NetUIHWND; INSTANCE:5]", "left", $clicks, $x, $y)

      EndIf
   EndIf
EndFunc

While True ;Not _IsPressed("1B")
    $aMousePos = MouseGetPos()
    $hControl=_WindowFromPoint($aMousePos[0],$aMousePos[1])
    ; Since _WindowFromPoint() can return 'sub' windows, or control handles, we should seek the owner window
    $hWin=_WinAPI_GetAncestor($hControl,2)
    If $hWin <> $hOldWin Then
        ;TrayTip("Window Info","Window under mouse = " & WinGetTitle($hWin), 1)
        $hOldWin = $hWin
    EndIf
    Sleep(10)
WEnd

我还没有弄清楚如何防止滚动影响笔记页面本身。如果有人找到了阻止滚动事件从注释列表区域内到达主要注释区域的方法，请分享您的解决方案，以便我们结合使用脚本以达到最佳效果。
