更改VIM中接下来的N个字符
假设我有以下行：
|add_test() (| == cursor position)
并且想要将“add”替换为“del”。
del|_test()
我可以按 X 三次，然后按 i 插入并输入 del。 我想要的是像 3c 或 3r 这样的东西来覆盖 3 个字符。 这两个都没有达到我想要的效果，3c 用相同的内容覆盖 3 个字符 角色，3r 还做了其他几件事。
有没有一种简单的方法可以做到这一点，而无需手动 Xing 和插入文本？
Say I have the following line:
|add_test() (| == cursor position)
And want to replace the 'add' with a 'del'.
del|_test()
I can either press X three times and then press i to insert and type del.
What I want is something like 3c or 3r to overwrite just 3 characters.
Both of these don't do what I want, 3c overwrites 3 characters with the same
character, 3r does several other things.
Is there an easy way to do this without manually Xing and inserting the text?

3s，“替换3个字符”与c3l相同。3cl和c3l应该是相同的，我不知道为什么你会看到相同的字符重复。我也喜欢使用t，例如另一张海报提到的ct_，这样我就不必计算字符数，只需输入“del”即可。我也为“替换几个字符”而苦苦挣扎了几天； 'r' 非常适合单个字符，
R非常适合匹配长度的字符串，但我想要像OP所要求的东西。于是，我输入:help x看了一会儿，发现s和S的描述只有几页纸从x向下。换句话说，
:help是你的朋友。阅读和学习。3s, "substitute 3 characters" is the same asc3l.3clandc3lshould be the same, I don't know why you'd see the same character repeated. I'm also a fan of usingt, e.g.ct_as another poster mentioned, then I don't have to count characters and can just type "del".I struggled with the "replace a couple of characters" for a few days too; 'r' was great for single characters,
Rwas great for a string of matching length, but I wanted something like the OP is asking for. So, I typed:help xand read for a while, it turns out that the description ofsandSare just a couple of pages down fromx.In other words,
:helpis your friend. Read and learn.使用c{motion}命令：
该单词由iskeyword变量确定。使用 :set iskeyword? 检查并删除任何“_”，例如 :set iskeyword=@,48-57,192-255。
顺便说一句，如果您想要更多信息，请参阅:help c和:helpmotion。
Use c{motion} command:
The word is determined by iskeyword variable. Check it with :set iskeyword? and remove any '_', like that :set iskeyword=@,48-57,192-255.
By the way see :help c and :help motion if you want more.
我认为
3cl就是你想要的。它向右改变 3 个字符。我会输入ct_del，但这不是您要求的I think
3clis what you want. It changes 3 characters to the right. I'd typect_del<esc>, but that's not what you askedc3('c', '3', space)，然后键入要插入的字符。 （或者您可以使用右箭头或l而不是空格。）或者，正如 @Mike 刚刚在评论中所说，如果字符数恰好满足，则
R效果很好。匹配您要删除的字符数。或者
ct_从光标更改到下一个_字符。或者，正如 @bloody 在评论中建议的那样，
3s。c3('c', '3', space), then type the characters you want to insert. (Or you can use right-arrow orlrather than space.)Or, as @Mike just said in a comment,
Rworks nicely if the number of characters happens to match the number of characters you're deleting.Or
ct_to change from the cursor to the next_character.Or, as @bloody suggests in a comment,
3s.如果作品长度相同，您可以使用 R 命令将您之前输入的内容替换为您输入的内容。
If the works have the same length you can use the
Rcommand which replaces what you had previously with what you type.给出的其他答案使用数字。当文本较长时，就更容易不必计数。例如，我经常在 markdown 文件中制作标题，例如：
一些我不想计算的超级长标题
用
yy双行pp一些超级长的标题，我不想计数
一些我不想数的超长标题
使用
V突出显示整行然后使用
r{char}或在本例中r=来获取：一些我不想计算的超级长标题
=================================================== ===========
（我在上面添加了一个空格来旅行堆栈溢出的降价格式）
The other answers given use numbers. When the text is longer it's easier to not have to count. For example I often make headlines in markdown files like:
Some super duper long title that I don't want to have to count
double the line with
yyppSome super duper long title that I don't want to have to count
Some super duper long title that I don't want to have to count
Highlighth the whole line with
Vthen use
r{char}or in this caser=to get:Some super duper long title that I don't want to have to count
