A snippet can be created in three ways:
Creating a snippet from a selection of steps: Select one or more steps (must be steps that can be grouped and not a single Group step) and you then select the action 'Create snippet from selection' . This will prompt you for a name for the new snippet, create a snippet of that name containing the select steps and insert a new Snippet step instead of the selected steps.
Creating a snippet by turning a group step into a snippet step: Select a Group step and then select the action 'Convert group to snippet' . This will prompt you for a name for the new snippet, create a snippet of that name containing the steps of the group and insert a new Snippet step instead of the selected Group step.
Create a snippet by selecting New Snippet in the File menu. A wizard will appear, that prompts you to give the name the snippet. After creating the snippet, an empty snippet will appear in your project, and an editor for the snippet will open. Please note, that you cannot edit the snippet contents (the steps inside the snippet) inside this editor, only edit the Description and the referenced variables list.
