description: 'Grouping multiple shapes during annotation.'
---
This feature allows us to group several shapes.
You may use the `Group Shapes` button or shortcuts:
- `G` — start selection / end selection in group mode
- `Esc` — close group mode
- `Shift+G` — reset group for selected shapes
You may select shapes clicking on them or selecting an area.
Grouped shapes will have `group_id` filed in dumped annotation.
Also you may switch color distribution from an instance (default) to a group.
You have to switch `Color By Group` checkbox for that.
Shapes that don't have `group_id`, will be highlighted in white.
