** 输入 dw 可以从光标处删除至一个单词的末尾。**
# example
---> Tha words don't |belong paper in this sentence.

许多改变文本的命令都由一个操作符和一个动作构成。
使用删除操作符 d 的删除命令的格式如下:
d motion
其中:
d - 删除操作符。
motion - 操作符的操作对象(在下面列出)。
简单的动作列表:
w - 从当前光标当前位置直到下一个单词起始处,不包括它的第一个字符。
e - 从当前光标当前位置直到单词末尾,包括最后一个字符。
$ - 从当前光标当前位置直到当前行末。
因此输入 de 会从当前光标位置删除到单词末尾。
** 在动作前输入数字会使它重复那么多次。 **
# example
---> This is just a |line with words you can move around in.
1. 输入 2w 使光标向前移动两个单词。
---> This is just a line with |words you can move around in.
2. 输入 3e 使光标向前移动到第三个单词的末尾。
---> This is just a line with words you can| move around in.
3. 输入 0 (数字零) 移动光标到行首。
---> |This is just a |line with words you can move around in.
# 使用格式
d number(数字) motion
# example
---> this |ABC DE line FGHI JK LMN OP of words is Q RS TUV cleaned up.
$ d2w
---> this |line FGHI JK LMN OP of words is Q RS TUV cleaned up.
$ d3e
---> this line |OP of words is Q RS TUV cleaned up.

# exmample
