Horizontal wrapping always involves a vertical movement; that is, the cursor
moves to the next or the preceding line.
Horizontal wrapping is affected by the setting of the Line Wrap option:
• When you press the cursor left ( . - ) key while the Line Wrap option is
on, the cursor moves to the last position of the bottom line of the viewport
after it reaches the top position of the viewport.
• When you press the cursor right ( -+- ) key while the Line Wrap option is
off, the cursor moves to the first column of the current line.
Vertical wrapping is not affected by the setting of the Line Wrap option.
