Table of contents not displaying custom text in field

[tukae]

You are supposed to be able to customize the headings in the table of contents using "Mark Table of Contents Entry" shift+option+command+O (Windows: shift+alt+O) but I can't get it to work. Here's an example of what I'm trying to do. Chapter headings are set to style heading 1:

Table of Contents
1
2
3

Body of document

1{ TC "Chapter One" \f C \l "1" }
Lorem ipsum...

2{ TC "Chapter Two" \f C \l "1" }
Lorem ipsum...

3{ TC "Chapter Three" \f C \l "1" }
Lorem ipsum...​

After refreshing the TOC, it should show as below but it doesn't:

Table of Contents
Chapter One
Chapter Two
Chapter Three​

What am I doing wrong? I've been using Mac Word 2011 and Windows Word 2010 with the same results.
