$　　　　　　　　　Move to end of line.　移动光标到行尾．

[n]w          The w command moves the cursor forward one word at a time, counting symbols and punctuation as equivalent to words. w 命令使得光标每次向前移动一个单词的距离，单词不仅仅指英文中的单词，还包括标点符号．

[n]W　　　You can also move by word, not counting symbols and punctuation, using the W command. (You can think of this as a “large” or “capital” Word.)　大写的w命令使得光标每次向前移动一个单词的距离，而这个单词不包括标点符号．

[n]b　　　To move backward by word, use the b command. CapitalB allows you to move backward by word, not counting punctuation.　ｂ命令使得光标向后移动一个单词，对应大写的ｂ向后移动光标的单词不包括标点符号．

上面移动单词的命令是指一个单词的距离，如果移动ｎ个单词，就在命令前面加个数字ｎ.

[n]G         To move to a specific line, you can use the G command. Plain G goes to the end of the
file, 1G goes to the top of the file, and 42G goes to line 42. 让光标移动到特定的行，那就用Ｇ命令吧．Ｇ前面的数字就代表那行．
