The Operations panel includes the list of those operations which can be performed in the given query. It is important to note that different operations appear in the panel if we click on the left mouse button over the empty field in the list or over an existing item.
If we click on an empty field, then the operations panel includes the following 3 buttons:
| • | Add new group: We can create a new group into the group list. |
| • | Delete list: All the items will be deleted in the Expression groups list |
| • | Import group: We can import previously saved group into our actual query |

If we click on a list item in the expression groups list, then the operations panel will include the following possibilities:
| • | Add new group: We can create a new group into the group list. |
| • | Delete selection: We can delete the actually selected group |
| • | Export group: The selected group will be exported to a separate file, which can be used later in other queries |
| • | Modify: We can modify the parameters of the selected group |
| • | Clone group: Makes a copy of the actual group to the list |
| • | Rename: We can change the name of the group |
