You have to turn off the graphics hot keys that flip the screen. If you're on Windows, you need to right click on the Windows desktop and select "Graphics Properties..." (or something similar depending on your version of Windows). This will bring up a screen where you can manage graphics and display options, look for a place where you can disable hot keys, sometimes it's hidden under something like "Options and Support". Turn off the CTRL + ALT + ↑ and CTRL + ALT + ↓ hotkeys (alternatively you can just disable all graphics hot keys if you're not using them).

如果你想复制一行到剪贴板，你也可以使用这个技巧:

Ctrl-Alt-Down 紧随其后的是 Ctrl-X

缺点是复制该行的文件变脏了。

如果有人使用Mac电脑，CTRL + ALT + DOWN键不起作用。

试试，

alt+命令+下

它的工作原理。

Ctrl+Alt+Down复制当前行到下面像记事本++ (Ctrl+D)

如果你的整个屏幕是180°腐烂，那么你应该禁用你的热键设置。

右键单击—>图形选项—>热键—>禁用

现在你可以尝试快捷键Ctrl+Alt+Down

Ctrl+Alt+Down / Ctrl+Alt+Up翻转我的屏幕，所以我在Eclipse快捷方式中覆盖了它 窗口=>首选项=>常规=>按键。 搜索“dupl”可以找到Duplicate Lines命令。我重写了默认设置，并选择Ctrl+Shift+D。对我来说，这很容易记住，就像Ctrl+D删除行一样
