斷行符號符(CR)和分行符號(LF)
CR（Carriage Return, 0Dh）——\n
LF（Line feed, 0Ah），——\r
斷行符號(CR)和換行(LF)符都是用來表示“下一行”的。而標準沒有規定要使用哪一個。於是產生了三種不同的用法：
Dos和windows採用斷行符號+換行(CR+LG)表示下一行（亦即所謂的PC格式，誰讓MS最早雄踞PC市場呢，^_^），
UNIX採用分行符號（LF）表示下一行，
MAC機採用斷行符號符（CR）表示下一行。

 

• In Normal, the text will be searched literally.
• In Extended, special character sequences will be interpreted as special characters such as newline characters. In this case, you can choose from:
  • \\ - Backslash character;
  • \t – TAB character;
  • \r – CR character;
  • \n – LF character;
  • \0 – NULL character;
  • \x## - Hexadecimal value (between 00 and FF);
  • \u#### - Extended hexadecimal value (between 0000 and FFFF, meant for Unicode characters);
  • \d### - Decimal value (between 000 and 255);
  • \o### - Octal value (between 000 and 377);
  • \b######## - Binary value (between 00000000 and 11111111).
• In Regular Expression, the query will be handled like a regular expression (POSIX).

The search direction determines to what relative direction of the cursor will be searched. Up means text before the cursor will be searched, Down means text beyond the cursor will be searched.

To find the (next) hit, press Find Next (or Enter). Count will count the amount of hits the search will result in.Find all in all opened documents will search all opened documents and displays a list of results for each file, see also Searching in Files. Find all in current documents behaves in a very similar way.

Close simple closes the search dialog (close button and ESC do the same).
