我已经为Eclipse编写了linecopypaste插件，它模仿了Visual Studio的复制/剪切/粘贴行为。我还发现了copycutcurrentline，它似乎做了同样的事情。

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

按Ctrl-D会删除一行 Ctrl-Z将取消删除，高亮显示整行 按Ctrl-X/C剪切或复制整行

与按Ctrl-Alt-Down再按Ctrl-X相比，其他用户建议的优点是它不会使eclipse认为文件以任何方式被更改。它也更快，即使用户使用Ctrl-Alt-Down/Up快捷键旋转屏幕也不会出现任何问题。因此，不需要为此重新映射捷径。

另一种方法是按Alt-Shift-Up，直到整条线都被选中。如果你走得太远，当然你可以用Alt-Shift-Down选择更少。

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).

Ctrl +alt+下/上/左/右作为热键优先于eclipse设置。作为替代，我尝试了不同的方法。

Step 1: Triple click the line you want to copy & press `Ctrl`-`C`(This will
select & copy that entire line along with the `new line`).
Step 2: Put your cursor at the starting of the line where you want to to paste
your copied line & press `Ctrl`-`V`.(This will paste that entire line & will
push previous existing line to the new line, which we wanted in the first place).
