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。

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Eclipse中，我们可以将任何命令分配给任何给定的操作 从菜单栏转到 窗口>首选项 然后寻找钥匙 然后搜索复制行 然后单击复制行，然后单击绑定中的命令 并执行一个命令，你想使用复制行我使用ctrl+shift+d 你可以选择任何你想要的

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!
