\n       新行
.        匹配任意字符

[]       匹配所有在 符号"[]"闭合区间内 的任意字符, 例如: "[ab]" matches "a" and "b". "[0-9]" matches any digit.
[^]      匹配所有不在  符号"[]"闭合区间内  的任意字符, 例如: "[^ab]" 匹配所有除了"a"和"b"之外的字符, "[^0-9]" 匹配所有非数字字符
*        匹配符号"*"的左边字符(0次或多次) 例如:"be*" 匹配 "b", "be" , "bee"
+        匹配符号"+"的左边字符(1次或多次) 例如:"be+" 匹配 "be" and "bee", 但不匹配 "b"

$        匹配符号"$"的左边字符串, 并且该字符串必须在行尾, 例如: AB$ 匹配字符串"AB",并且该"AB"必须在行尾
()       Affects evaluation order of expression and also used for tagged expression.
\        Escape character. If you want to use character "\" itself, you should use "\\".


技巧:
1. 查找空行 : "^[ \t]*\n"
2. 查找行首序号: "^[0-9. ]+"
   例如: 
   "
      1. aaaa
      2. bbbb
      :
      100. abcd
      :
   "
3. 查找"["和"]"之间的内容: "\[.+\]"
4. 匹配<b></b>之间的内容(包括<b></b>):"^\<b\>.+\</b\>"
5. 匹配<b>...<br/>之间没有"/"字符的内容:"^\<b\>[^/]+\<br/\>"
   例如:
      ...
      <b>appeal</b> - v. to take to <br/>
      <b>somebody for help <br/>
      <b>appoint</b> - v. to name;<br/>
      <b>statues <br/>
      ...
      
      使用:^(\<b\>)([^/]+\<br/\>) 和替换串"\2", 将使得以上的第2行和第4行变成:
      ...
      <b>appeal</b> - v. to take to <br/>
      somebody for help <br/>
      <b>appoint</b> - v. to name;<br/>
      statues <br/>
      ...

The tagged expression is enclosed by (). Tagged expressions can be referenced by \0, \1, \2, \3, etc. \0 indicates a tagged expression representing the entire substring that was matched. \1 indicates the first tagged expression, \2 is the second, etc. See following examples.

Original Search  Replace  Result 
abc      (ab)(c) \0-\1-\2 abc-ab-c
abc      a(b)(c) \0-\1-\2 abc-b-c
abc      (a)b(c) \0-\1-\2 abc-a-c
