This page explains the difference between a part and a group, which is not depth but meaning. Both are one line that holds several, so on screen they look alike — but they describe different things, and the list treats them differently.
The difference in one sentence
A group holds the steps inside one item. A part holds items of the running order.
A pdf that became eight slides is one item with eight steps: that is a group. “Welcome”, holding four things that happen one after another during the welcome: that is a part.
You can see it in the list. What sits in a group is a step within one thing, so it goes black on the list background. What sits in a part keeps the ordinary list colour, because each of those lines is a cue in its own right.
Making one
The arrow beside the Group button in the toolbar → Part. It appears at the top level: a part is never inside something else.
Its own numbering, or counting on
Right-click the part header to choose:
| Choice | What the numbers do |
|---|---|
| Own numbering, starts at 1 | The part carries a number, and its items start again at 1. What you read on the lines leaves the part’s number off — it is already on the part’s own line. |
| Count on with the list | The part gets no number at all and its items simply carry on with the rest of the list. |
The first is right for a programme built out of named blocks, where “item 3 of part 2” is how people talk. The second is right when the part is only a heading for the eye and the running order should read 1 … 40 straight through.
When to use which
| Situation | Use |
|---|---|
| A presentation, pdf or song that became several lines | Group |
| The sections of a service or programme | Part |
| A block you want to collapse out of the way | Either — both collapse |
| Something you want to hand to another location as a file | Group (a part is a heading, not a package) |
If you are unsure, ask whether the lines inside are steps of one thing or things in their own right. That answer is the setting.
