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

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).

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

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。

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。

在MAC中试试这个。

alt+命令+下

它的工作原理。
