Vedeu.trigger(:_cursor_reposition_, name, y, x)

:cursor(up, down, left, right)_

Vedeu.trigger(:_cursor_up_)
Vedeu.trigger(:_cursor_down_)

• The cursor or view may not be visible, but it will still move if requested.
• The cursor will not exceed the border or boundary of the interface, or boundary of the visible terminal.
• The cursor will move freely within the bounds of the interface, irrespective of content.
• The view will not exceed the boundary of the visible terminal, though its offset may (this means content will appear to have scrolled).
• The view will move freely within the bounds of the interface, irrespective of content.
