    - `force_ephemeral` - same as ephemeral, but converts existing single windows groups.

+   - `untab` will untab the group if it was previously tabbed
+   - `opposite` will toggle between horizontal and vertical layouts if the group is not tabbed.
+ - `hy3:setephemeral, <true | false>` - change the ephemerality of the group the node belongs to
  - `hy3:movefocus, <l | u | d | r | left | down | up | right>, [visible]` - move the focus left, up, down, or right
