Answer 1

• Ctrl + H
• 查找内容：(?<![A-Z])([A-Z])([A-Z]+.+$)＃1rst选项 或
• 查找内容：(?<![A-Z])([A-Z])([A-Z]+)(?![A-Z])＃第二个选项
• 替换为：$1\L$2
• 检查匹配大小写
• 检查环绕
• 检查正则表达式
• 取消检查. matches newline
• 全部替换

说明：

第一个选项

(?<![A-Z])      # negative lookbeahind, make sure we haven't upper before
([A-Z])         # group 1, 1 upper
(               # group 2
  [A-Z]+        # 1 or more upper
  .+            # 1 or more any character but newline
  $             # end of line
)               # end group 2

或第二个选项

(?<![A-Z])      # negative lookbeahind, make sure we haven't upper before
([A-Z])         # group 1, 1 upper
([A-Z]+)        # group 2, 1 or more upper
(?![A-Z])       # negative lookahead, make sure we haven't upper after

替换： 两个选项相同

$1          # content of group 1 (the first upper letter)
\L$2        # lowercased the content of group 2, the other letters
