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).

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

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

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。

(在Windows上测试)[根据以下评论，也适用于Ubuntu, IBM RTC 4 / RSA 9]

在Eclipse中，按Ctrl+Shift+L 2 (或按Ctrl + 3 > type: Keys > Enter)。 在“键入筛选文本”(搜索)文本框中，键入“复制行” 选择筛选行，右键单击“Binding”字段，然后选择全部 按Ctrl + Shift + V 给好

从现在开始，对于任何你想复制的行，只需按Ctrl+Shift+V。
