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).

Ctrl-Alt-Down:将当前行或所选行复制到下方

Ctrl-Alt-Up::复制当前行或选定的行到上面

Ctrl-Shift-L:弹出快捷键列表

它和我一起工作， Eclipse + Spring工具套件。

alt+命令+下

按Ctrl-D会删除一行 Ctrl-Z将取消删除，高亮显示整行 按Ctrl-X/C剪切或复制整行

与按Ctrl-Alt-Down再按Ctrl-X相比，其他用户建议的优点是它不会使eclipse认为文件以任何方式被更改。它也更快，即使用户使用Ctrl-Alt-Down/Up快捷键旋转屏幕也不会出现任何问题。因此，不需要为此重新映射捷径。

另一种方法是按Alt-Shift-Up，直到整条线都被选中。如果你走得太远，当然你可以用Alt-Shift-Down选择更少。

(在Windows上测试)[根据以下评论，也适用于Ubuntu, IBM RTC 4 / RSA 9]

在Eclipse中，按Ctrl+Shift+L 2 (或按Ctrl + 3 > type: Keys > Enter)。 在“键入筛选文本”(搜索)文本框中，键入“复制行” 选择筛选行，右键单击“Binding”字段，然后选择全部 按Ctrl + Shift + V 给好

从现在开始，对于任何你想复制的行，只需按Ctrl+Shift+V。
