将文本从行首复制到光标位置:ctrl + insert

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

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).

alt+命令+下

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:)

如果有人使用Mac电脑，CTRL + ALT + DOWN键不起作用。

试试，

alt+命令+下
