Sets the layout mode of the focused container. _mode_ can be one of _splith_,
_splitv_, or _toggle split_.
**mode** <mode_name>::
Switches to the given mode_name. the default mode is simply _default_. To
create a new mode in config append _{_ to this command, the following lines

Moves the focused container _left_, _right_, _up_, or _down_.
