h   move one character left
j   move one row down
k   move one row up
l   move one character right
w   move to beginning of next word
b   move to previous beginning of word
e   move to end of word
W   move to beginning of next word after a whitespace 大写的区别在于只使用空格作为分割标准
B   move to beginning of previous word before a whitespace
E   move to end of word before a whitespace

举个例子

Vim provides many ways to move the cursor. Becoming familiar w

当光标在 cursor 的时候，如果使用 w，将会定位到句号，但是当使用 W，将会定位到 B。因为 W 只认为空格是单词分割符。
同理：对于 b 和 B，如果光标在 Becoming 第一个字符，如果使用 b 将会定位到句号，但是 B 将会定位到 cursor
对于 e 和 E，如果光标在 cursor 第一个字符，那么如果使用 e 竟会定位到 r，但是 E 将会定位到句号。

虽然大多数情况下，大写看上去表现一致，但是我们需要知道原因，因为没有其他符号。

All the above movements can be preceded by a count; e.g. 4j moves down 4 lines.
