I published a Word document of the Visual Visio sections I found to my download page.

The document contains cells from CellsSRC() that do not appear in the visual sections. They are highlighted in red in the document. Though there are some that are labeled as Unused or have nonsense names, there are some that are interesting.

Text Block Format | TextMaxDepth, TextGeometry, TextContainer |
Text Fields | Type, UICat, UICod, UIFmt |

Notes:
- The UI* entries are for backword compatability.
- David Parker did a blog about ShapeKeywords.
- Some of the others look tempting to explore
