Vim：在多行中插入相同的字符

有时我想跨多行编辑某个视觉文本块。

例如，我会采用如下所示的文本：

name
comment
phone
email

并让它看起来像这样

vendor_name
vendor_comment
vendor_phone
vendor_email

目前我现在要做的方式是......

1. Select all 4 row lines of a block by pressing V and then j four times.
2. Indent with >.
3. Go back one letter with h.
4. Go to block visual mode with Ctrlv.
5. Select down four rows by pressing j four times. At this point you have selected a 4x1 visual blocks of whitespace (four rows and one column).
6. Press C. Notice this pretty much indented to the left by one column.
7. 键入一个" vendor_"没有报价。请注意我们必须放回的额外空间。
8. Press Esc. This is one of the very few times I use Esc to get out of insert mode. Ctrlc would only edit the first line.
9. 重复步骤 1。
10. Indent the other way with <.

I don't need to indent if there is at least one column of whitespace before the words. I wouldn't need the whitespace if I didn't have to clear the visual block with c.

但是，如果我必须清除，那么有没有一种方法可以完成我上面执行的操作，而无需创建带有缩进的所需空白？

Also why does editing multiple lines at once only work by exiting out of insert mode with Esc over Ctrlc?

这是一个更复杂的例子：

name    = models.CharField( max_length = 135 )
comment = models.TextField( blank = True )
phone   = models.CharField( max_length = 135, blank = True )
email   = models.EmailField( blank = True )

to

name    = models.whatever.CharField( max_length = 135 )
comment = models.whatever.TextField( blank = True )
phone   = models.whatever.CharField( max_length = 135, blank = True )
email   = models.whatever.EmailField( blank = True )

在此示例中，我将在.，然后在插入模式下将其重新插入，即键入.whatever.。希望现在您可以看到此方法的缺点。我仅限于选择一列文本在垂直位置上都是一样的.

1. 将光标移至n in name.
2. Enter visual block mode (Ctrlv).
3. Press j three times (or 3j) to jump down by 3 lines; G (capital g) to jump to the last line
4. Press I (capital i).
5. Type in vendor_. Note: It will only update the screen in the first line - until Esc is pressed (6.), at which point all lines will be updated.
6. Press Esc.

一个大写I必须使用小写字母i，因为小写i被解释为一个的开始文本对象 http://vimhelp.appspot.com/motion.txt.html#text-objects，它本身就相当有用，例如用于在标签块内选择（it http://vimhelp.appspot.com/motion.txt.html#it):
