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).

另一种快捷方式是按Ctrl+Shift+L并选择要执行的命令并按enter

这是初学者的最佳练习。

在MAC中试试这个。

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
