在Mac上，我尝试了linecopypaste，效果很好 cmd+c ->复制当前(未选中)行，就像Vi/Vim中的“yy”命令一样 cmd+v ->粘贴，就像Vi/Vim中的“p”命令一样

感谢Larsch的工作!

PD:在优胜美地使用Eclipse Luna 4.4.2

在MAC中试试这个。

alt+命令+下

它的工作原理。

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。

对于mac, shift+alt+down_arrow在netbeans的编辑器中工作。

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).

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。
