GROUP (Ctrl+G)

--------------

Creates a new parent object containing all selected objects.

In Hierarchy:

- Creates "Group" or "UI Group" (for RectTransform objects)

- Preserves sibling order (group inserted at last selected position)

- Calculates appropriate pivot based on settings

- For UI: automatically sizes the group to fit all children

In Project:

- Creates a new folder and moves selected assets into it

- Works with both files and folders

In Timeline:

- Creates a new Group Track containing selected tracks

UNGROUP (Alt+G)

---------------

Moves children up one level and deletes the parent object.

In Hierarchy:

- Moves all children to the parent's parent

- Deletes the original parent object

- Shows confirmation for prefabs (will unpack) or objects with components

- Selects all extracted children after operation

In Project:

- Moves folder contents up one level

- Deletes the empty folder

In Timeline:

- Moves tracks out of a Group Track

- Deletes the Group Track

EXTRACT (Shift+Alt+G)

---------------------

Like Ungroup, but keeps the parent object intact.

In Hierarchy:

- Moves all children up one level

- Parent object remains (becomes childless)

- Useful when parent has components you want to keep

In Project:

- Moves folder contents up one level

- Folder remains (becomes empty)

In Timeline:

- Moves tracks out of a Group Track

- Group Track remains (becomes empty)
