win_splitmove({nr}, {target} [, {options}]) *win_splitmove()*
Move the window {nr} to a new split of the window {target}.
This is similar to moving to {target}, creating a new window
using |:split| but having the same contents as window {nr}, and
then closing {nr}.
Temporarily switch to window {target}, then move window {nr}

Both {nr} and {target} can be window numbers or |window-ID|s.
Both must be in the current tab page.

Move the window {nr} to a new split of the window {target}.
This is similar to moving to {target}, creating a new window
using |:split| but having the same contents as window {nr}, and
then closing {nr}.
Temporarily switch to window {target}, then move window {nr}
to a new split adjacent to {target}.
Unlike commands such as |:split|, no new windows are created
(the |window-ID| of window {nr} is unchanged after the move).
Both {nr} and {target} can be window numbers or |window-ID|s.
Both must be in the current tab page.
