The document [www.sidefx.com] has a section about "Working with patterns".
But I genuinely can't understand it. Like the first action we can do is:
> Change a pattern for an item
> Double-click the name of the item.
> Type in the desired pattern.
> Press Enter.
...what is "an item"? An item in selection set pane? But when I double-click an item in selection set pane, it simply let me rename that item. What does it do with "pattern"?
