对于个人使用，我添加了一个vim插件，如Vrapper到Eclipse，只使用yy复制整行。

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

在我的Mac上，默认设置是ALT+CMD+Down

您可以通过Eclipse -> Preferences(快捷键CMD+)和General -> Keys来更改/查看所有键绑定

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

看到Windows /首选项- >常规- >键。

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).

将文本从行首复制到光标位置:ctrl + insert

这是有效的，为我节省了很多时间。
