我对页面向上，页面向下的intellij中的滚动行为不满意。感觉不对劲。总觉得我好像离开了范围。
是否可以调整向上翻页的页面大小？也许是半页或类似的。

无法通过设置控制此操作。你可以做的是编写一个插件，以你喜欢的方式执行滚动。这很简单：您需要做的就是复制现有的PageUpAction / PageDownAction类及其调用的方法（EditorActionUtil。moveCaretPageUp / Down），以便根据需要滚动。

我接受了@yole的回答，并执行了他在单独的插件中描述的所有动作：
无法通过设置来控制此设置。您可以做的是编写一个插件，以您喜欢的方式执行滚动。这很简单：您需要做的就是复制现有的 PageUpAction / PageDownAction类及其调用的方法 （EditorActionUtil.moveCaretPageUp / Down）进行任意滚动。
此插件实现了“部分向上翻页”和“部分向下翻页”新动作，使它们能够在通常的IDEA设置对话框中滚动定义可定义的屏幕大小。
official JetBrains repository中有一个可安装的插件版本。

由于许多人对此进行了询问，因此对于 mac用户，这可以全局控制，而不是使用 karabiner 应用程序在页面上/下滚动并添加以下复杂规则：

还请注意，要获得平滑的滚动效果，请考虑下载 Mos应用程序，并根据需要调整首选项。
这可能会在Mac上产生其他后果，因此您可能需要调整其他内容，因为page_up / down不再是page_up / down ，而是鼠标滚动。
