Mac 下思源如何调整 shift+home/end 选中至行首 / 行尾而非页首 / 页尾？

我创建了如下文件~/Library/KeyBindings/DefaultKeyBinding.dict，修改了 Mac 的按键映射

{
/* Remap Home / End keys to be correct */
"\UF729" = "moveToBeginningOfLine:"; /* Home */
"\UF72B" = "moveToEndOfLine:"; /* End */
"$\UF729" = "moveToBeginningOfLineAndModifySelection:"; /* Shift + Home */
"$\UF72B" = "moveToEndOfLineAndModifySelection:"; /* Shift + End */
"^\UF729" = "moveToBeginningOfDocument:"; /* Ctrl + Home */
"^\UF72B" = "moveToEndOfDocument:"; /* Ctrl + End */
"$^\UF729" = "moveToBeginningOfDocumentAndModifySelection:"; /* Shift + Ctrl + Home */
"$^\UF72B" = "moveToEndOfDocumentAndModifySelection:"; /* Shift + Ctrl + End */
}
​

目前无论是 vscode 还是 onenote，以上规则都运行良好，但唯独在思源中我按下 shift+end 选中的是光标至页未而非行尾，shift+home 同理。我很困惑这是为什么，希望有人能给予解答。
