Created attachment 182509 [details] all six kind of anchoring Open attached document. It has on the first slide the six cases of anchoring available in PowerPoint. The second slide contains an image of how it looks in PowerPoint. There is no wrap in the examples to force the text to overflow and so make the anchor position better visible. The text direction tb-rl is not rendered by text rotation but is a native writing mode of the edit engine. Therefore anchor position needs special treatment on import and export.
