IBM 3164 ASCII Manual page 40

Line feed (LF) key
If there is more than one line of null characters in an unprotected field, the last
null line is lost.
If there are no null character lines, the audible alarm sounds and WRONG
PLACE is displayed in the operator information area.
If the page is formatted, the insert line operation is limited to the current
unprotected field.
The current unprotected field must have at least one line of null characters.
As a result of the insert line operation, the MDT bit is set to 1, and the cursor
moves to the first character position of the newly created line. If the cursor is
in a protected field or if there is an attribute on the cursor line, the audible
alarm sounds and WRONG PLACE is displayed in the operator information
area.
In echo mode, the Insert Line response is transmitted to the host and no local
function is performed.
Note:
As a result of the insert line operation, a line attribute with the same
characteristics will be created at the cursor location.
Moves the cursor to the next partition
When you press this key, the cursor moves from the viewport of the currently
activated partition to the viewport of the partition with the next higher
viewport identifier (VI D) value on the same screen. If no higher VI 0 value
exists, the cursor goes to the viewport with the lowest VIO value. The page
and partition associated with the viewport to which the cursor moves become
the active page and partition .. The cursor is placed at the current cursor
address (CCA) for that page/partition. If only one viewport exists on a screen
(viewport type
=
1), this key has no effect.

ASCII LF option is off, or to the first position of the next line if the option is
on.
