IntelliJ IDEA way of editing multiple lines
提问by hdx
I've seen this done in TextMate and I was wondering if there's a way to do it in IDEA.
我已经在 TextMate 中看到了这一点，我想知道是否有办法在 IDEA 中做到这一点。
Say I have the following code:
假设我有以下代码：
leaseLabel = "Lease";
leaseLabelPlural = "Leases";
portfolioLabel = "Portfolio";
portfolioLabelPlural = "Portfolios";
buildingLabel = "Building";
What is the best way to append '+ "foo"' to every line? Column mode won't work since the lines are not correctly aligned on the right side... unless there is an easy way to right justify the text :P
将 '+ "foo"' 附加到每一行的最佳方法是什么？列模式将不起作用，因为右侧的行没有正确对齐......除非有一种简单的方法可以右对齐文本：P

I just use the macros for this sort of thing. I start recording the macro, do it once, then play back the macro on each line I want to modify. You'd be amazed at how fancy you can get with the macro record/playback feature.
我只是将宏用于此类事情。我开始录制宏，执行一次，然后在要修改的每一行上播放宏。您会惊讶于宏录制/回放功能的奇妙之处。

In this case you can also just select the piece of code in which you want to do this and perform a replace on it. Replace:
";
with:
" + "foo";
So in case you didn't know: If you have text selected while you perform a replace (Ctrl+R or Cmd+R) it will only apply to the selected piece of text.
在这种情况下，您也可以只选择要执行此操作的代码段并对其执行替换。将：
";替换
为：
" + "foo";
因此，如果您不知道：如果您在执行替换（Ctrl+R 或 Cmd+R）时选择了文本，它将仅适用于选定的文本片段。

What I usually use (NetBeans, but I believe it is simple to use in any IDE) is find&replace.
我通常使用的（NetBeans，但我相信在任何 IDE 中使用都很简单）是find&replace.
You just find ;\nand replace it with + $foo;\nthen you don't apply to ALL lines but you place cursor on the first line and you just hit "replace" button (depends on your IDE I suppose) 7 times to change 7 lines in no time. Easy and simple and it should be done with the most basic and the most advanced IDE you can find.
您只需找到;\n并替换它，+ $foo;\n然后您就不会应用于所有行，但是您将光标放在第一行，然后您只需点击“替换”按钮（我想取决于您的 IDE）7 次即可立即更改 7 行。简单易行，应该使用您能找到的最基本和最先进的 IDE 来完成。
EDIT: In IntelliJ (don't know if it works in other IDEs too) you can use your regexp search&replace to selection only so you can actually use "replace all"
编辑：在 IntelliJ（不知道它是否也适用于其他 IDE）中，您可以仅使用正则表达式搜索和替换进行选择，这样您就可以实际使用“全部替换”

I use Column Selection Mode(Cmd+Shift+8on Mac) which allows to create multiple cursors via Shift+Upor Shift+Downthen edit all the lines together.
我使用列选择模式（Mac 上的Cmd+ Shift+ 8），它允许通过Shift+Up或Shift+创建多个光标，Down然后一起编辑所有行。
Starting from IntelliJ IDEA 14 there is also Clone Caret Above / Below:
从 IntelliJ IDEA 14 开始，还有Clone Caret Above/Below：
- Windows: Ctrl, Ctrl+Up/Down
- MacOS: Option,Option+ Up/Down
- 视窗：Ctrl, Ctrl+ Up/Down
- MacOS: Option, Option+ Up/Down
(hold the second press of the modifier key, then press the arrow key)
（按住修改键的第二次按下，然后按箭头键）

It took me a while to find out, but on a Mac you can double-press Option(press it once, release, press it again, keep it pressed) and use Up/Downkeys to create/remove carets as you wish.
我花了一段时间才发现，但在 Mac 上，您可以双击Option（按下一次，松开，再次按下，按住不放）并使用Up/Down键根据需要创建/删除插入符号。
You can also hold Shift+Optionand click to create/remove carets at specific points.
您还可以按住Shift+Option并单击以在特定点创建/删除插入符号。

Another keyboard-only approach. It's possible (since 13.1 version) to use Alt+J/ Shift+Alt+J(Ctrl+Gfor OS X) shortcuts for creating multiple carets. Alt+Jselects the next occurrence of the currently selected text and adds another caret.
另一种仅使用键盘的方法。可以（从 13.1 版本开始）使用Alt+ J/ Shift+ Alt+ J（OS X 为Ctrl+ G）快捷方式来创建多个插入符号。Alt+J选择当前选定文本的下一次出现并添加另一个插入符号。
- Select the first semicolon
- 选择第一个分号
- Then press Alt+Jfour times
- 然后按Alt+J四次
- Edit what you want to
- 编辑你想要的
- Press Escto return to the first line.
- 按Esc返回第一行。

You could also do a vertical code block selection by clicking mouse wheeland dragging:
您还可以通过单击鼠标滚轮并拖动来进行垂直代码块选择：

Place caret at end
将插入符号放在末尾
Windows:CTRL+ CTRL(Hold) + ↑ / ↓
视窗：CTRL+ CTRL（按住）+↑ / ↓
Mac:option+ option(Hold) + ↑ / ↓.
Mac：option+ option（按住）+ ↑ / ↓。
To place caret at the end of rows: move caret to top row, clone down to bottom, and click END.
要将插入符号放在行尾：将插入符号移动到顶行，向下复制到底部，然后单击END。
Change Multi-caret Hotkey
更改多插入符号热键
To add a custom Keymap, CTRL+SHIFT+A, type keymapand click on the one with Settingsas subtext. Search for Clone Caret Aboveand Clone Caret Below.
要添加自定义键盘映射，CTRL+ SHIFT+ A，键入keymap并单击带有Settings作为潜台词的那个。搜索Clone Caret Above和Clone Caret Below。
I mapped mine to ALT+SHIFT+↑ / ↓on Windows and ?+↑ / ↓on Mac.
我将我的映射到Windows上的ALT+ SHIFT+↑ / ↓和Mac上的?+ ↑ / ↓。
