*fullscreen*
Toggles fullscreen for the focused view.
*layout* splith|splitv|stacking|tabbed
*layout* default|splith|splitv|stacking|tabbed
Sets the layout mode of the focused container.
*layout* toggle split
Switches the focused container between the splitv and splith layouts.
*layout* toggle [split|all]
Cycles the layout mode of the focused container though a preset list of
layouts. If no argument is given, then it cycles through stacking, tabbed
and the last split layout. If "split" is given, then it cycles through
splith and splitv. If "all" is given, then it cycles through every layout.
*layout* toggle [split|tabbed|stacking|splitv|splith] [split|tabbed|stacking|splitv|splith]...
Cycles the layout mode of the focused container through a list of layouts.
*move* left|right|up|down [<px>]
Moves the focused container in the direction specified. If the container,
