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).

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。

我用的是Windows 7。要禁用它，我所做的就是右键单击Windows桌面，选择“图形属性”->选项。然后在结果屏幕的左侧选择“关闭”。禁用所有热键组合。我认为没有办法只禁用其中一些，要么全部禁用，要么完全禁用。反正我也不需要。所以现在crtl+Alt+Up和crtl+Alt+ down工作为我在Eclipse和我的屏幕保持不变:) 我认为类似的选项在其他版本的Windows中也存在。玩得开心!

这是另一种方法:

1) Alt+Up and Alt+Down (or Alt+Down and Alt+Up, order does not matter)
2) Ctrl+C

当然vim的“yy”是最快的:)

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。
