The Binary & Multiple Lines Window enables you to enter Binary & Multiple Lines for Find and Replace for Regular Expression searches. For Plain-text searches, this window enables you to enter only multiple lines. For other kinds of searches, the Binary & Multiple Lines Window is unavailable and does nothing.
Make one or more lines by typing directly into the editor in the window. You can paste into the editor any text that you cut or copied elsewhere. To add binary characters, type them in using the form \x00, that is, backslash-x followed by a 2-digit hexadecimal number, 00 to FF. Another way to enter a binary character is to double-click on a character in the table of characters to the right of the editor. (The table of characters is not visible or available for Plain-text searches, but for only Regular Expression searches.)
If a character is printable, it appears in the table of characters in its printable form. Thus an a appears as a. If a character is not printable, it appears as a hexadecimal number. So, for example, character #1B (#27 decimal) appears as 1B. If you double-click on 1B to insert it into the editor, it is inserted as \x1B.
NOTE that some double-clicked binary characters are inserted into the editor not as numbers, but as their commonly used representations. Characters #08-#0A and #0C-#0D are inserted as \b\t\n\f and \r, respectively.
The following are buttons that control the table of characters.
Insert Click to insert a selected character from the table into the editor at the position of the editors cursor. A character is selected when you click on it once in the table of characters.
Hide Hide the table of characters.
Char Show the tableof characters. This button is visible only when the table of characters has been hidden by clicking the Hide button.
When you click the OK button, what you have entered into the editor in this window is placed into the Find or Replace edit box on the Main Window according to which button you pressed, the one beside Find or the one beside Replace.
