Code groups help in organizing codes, they make it easy to access specific codes from a long list of codes, and they allow you to create any kind of filter you need for querying your data.
Code groups can be created in two ways -- you can create them in the Code Group Manager, or in the side panel of the Code Manager.
To open the Code Manager, double-click on the main code branch in the Project Explorer or click on the codes button in the toolbar and select Code Manager from the dropdown menu.
Select a few codes and drag them into the filter area on the left-hand side. After dropping the codes, the code group is automatically created. If you want to change the default name, left-click on the code group.
When you click on the newly created code group, only the codes from this group will show up in the list on the right-hand side. This allows you to quickly access codes in your list without having to scroll the list all the time.
To show all codes again, click on the minus (-) in the yellow pane that shows up on top of the code list when selecting a group.
