Only one left and one right margin can be set for a given display.
When the Less Than key is pressed, the previous left margin is
replaced by the new one. Any tab stop or audible 'end of line'
signal setting existing to the left of the new left margin is retained
and remains operable. If a right margin existed to the left of or
coincident with the new left margin, the right margin is reset to the
default position (last scale line position). The scale line is updated
accordingly.
When the Greater Than key is pressed, the previous right margin is
replaced by the new one. Any tab stop or audible 'end of line'
signal setting existing to the right of the new right margin is retained
and remains operable. If a left margin existed to the right of or
coincident with the new right margin, the left margin is reset to the
default position (first scale line position).
If an attempt is made to enter a right margin in the left-margin
default position, or vice versa, the input is ignored.

establishes the standard right margin.
(The standard right margin causes input to be inhibited when
character entry is attempted at the right margin position in
document mode with word wrap off.) You can establish an
alternative right margin by positioning the cursor on the right
margin symbol and pressing the Cursor Select key. The standard
right margin symbol is replaced with a broken vertical bar ( : ).
This alternative right margin symbol signifies that an automatic
margin release occurs at the right margin when word wrap is off;
that is, the right margin is ignored when word wrap is off. This is
useful in certain power typing situations. A second pressing of the
Cursor Select key reestablishes the standard margin symbol and
operation.
