  • Reverse: Pressing this key allows the operator to reverse the current cursor direction. It functions as follows:
    • The cursor is repositioned according to the current cursor direction. When right-to-left, the cursor is placed at the current left boundary location. When left-to-right, the cursor is placed at the current right boundary location.
    • The cursor direction is then reversed; the Keyboard Layer you get depends on the new cursor direction.
    • Insert mode is reset.
  • Close: By pressing this key, data entered in one key direction is joined with data that was previously entered in the opposite direction:
    • All embedded null characters are removed from the current line (or field, if the field is contained on one line).
    • Joined text is moved to the right boundary of the field if the field direction is right-to-left, or to the left boundary if the field direction is left-to-right.
    • The remainder of the line (or the field, if contained on one line) is padded with null characters.
    • The cursor direction is set to the field direction.
    • If the cursor direction is now left-to-right, the cursor is positioned at the first null character to the right of the joined text. If the cursor direction is now right-to-left, the cursor is positioned at the first null character to the left of the joined text.
    • Insert mode is reset.
