Table 12-6 Packet Filter Editor Commands

Command	Keys	Description
List buffer	Ctrl+l	Displays each of the lines in the editing buffer and then redisplays the line currently
		being edited
Next Line	Ctrl+n	Moves cursor to next line; positions cursor at start of line
Previous Line	Ctrl+p	Moves cursor to previous line; positions cursor at start of line
Start of Line	Ctrl+a	Moves cursor within a line to the start of the present line
End of Line	Ctrl+e	Moves cursor within a line to the end of the present line
Left 1 Character	Ctrl+b	Moves cursor left one character within a line
Right 1 Character	Ctrl+f	Moves cursor right one character within a line
Insert Line	Enter	Inserts a new line. The new line becomes the current line, with the cursor positioned at
		the start. If the cursor is positioned over the first character on a line when you press
		Enter, a blank new line is inserted prior to the current line. Otherwise, the current line is
		split at the cursor position, with the current line retaining the characters before the
		cursor, followed by the new line containing the remainder of the characters.
Delete Previous	Ctrl+h	Deletes a single character preceding the cursor and shifts the remainder of the line left
Character		one position
Delete Current	Ctrl+d	Deletes a single character under the cursor and shifts the remainder of the line left one
Character		position
Delete Line	Ctrl+k	Deletes the remainder of the line from the current cursor position. If the cursor is
		positioned over the first character, all of the characters on the line are deleted, but the
		line is retained. A second Delete Line command removes the line from the edit buffer.
Insert/Overstrike	Ctrl+o	Toggles between the insert mode and overstrike mode
Toggle
Write Changes	Ctrl+w	Writes (saves) the current contents of the edit buffer into the packet filter definition. No
		syntax checking of the definition is performed at this point other than to verify that the
		length of the source is within the maximum limits. If the source is too long, the message
		Error: Edit buffer exceeds maximum length is displayed. The
		contents of the edit buffer are unaffected; however, the packet filter definition contains
		only those lines that fit entirely within the length limitation.
Exit Editor	ESC	Allows you to leave the editor. You receive a warning if the edit buffer has not been
		successfully written since the last modification. You can either discard the changes or
		return to the editor. Note that only those changes made since the last Write Changes
		command are discarded.
