How do I promote/demote an entire branch? For example let's say I have the following table of contents:
1. Hello 2. World 2.1 How 2.2 Are 2.3 You If I demote the second heading using the Document->Outline sidebar, lyx will give me this: 1. Hello 1.1 World 1.2 How 1.3 Are 1.4 You In other words lyx will only demote the heading and ignore all of it's content thereby breaking the hierarchical structure of the document. Sometimes this is what I want, but more often than not, what I really need is for lyx to demote the entire branch of the tree giving me something like this: 1. Hello 1.1. World 1.1.1 How 1.1.2 Are 1.1.3 You As best as I can tell the only way of doing this in lyx is to manually demote every single subheading. This makes reorganising the structure of hierarchical documents unnecessarily time consuming. Is there a better way of doing this?
