GetWinid()->win_id2win()
+ win_move_separator({nr}, {offset}) *win_move_separator()*
+ Move window {nr}'s vertical separator (i.e., the right border)
+ by {offset} columns, as if being dragged by the mouse. {nr}
+ can be a window number or |window-ID|. A positive {offset}
+ moves right and a negative {offset} moves left. Moving a
+ window's vertical separator will change the width of the
+ window and the width of other windows adjacent to the vertical
+ separator. The magnitude of movement may be smaller than
+ specified (e.g., as a consequence of maintaining
+ 'winminwidth'). Returns TRUE if the window can be found and
+ FALSE otherwise.
+
+ Can also be used as a |method|: >
+ GetWinnr()->win_move_separator(offset)
+
+ win_move_statusline({nr}, {offset}) *win_move_statusline()*
+ Move window {nr}'s status line (i.e., the bottom border) by
+ {offset} rows, as if being dragged by the mouse. {nr} can be a
+ window number or |window-ID|. A positive {offset} moves down
+ and a negative {offset} moves up. Moving a window's status
+ line will change the height of the window and the height of
+ other windows adjacent to the status line. The magnitude of
+ movement may be smaller than specified (e.g., as a consequence
+ of maintaining 'winminheight'). Returns TRUE if the window can
+ be found and FALSE otherwise.
+
+ Can also be used as a |method|: >
+ GetWinnr()->win_move_statusline(offset)
+
win_screenpos({nr}) *win_screenpos()*
Return the screen position of window {nr} as a list with two
numbers: [row, col]. The first window always has position
