When composing a document, and the user wishes to add a comment, once you press the Control+Alt+C keybinding to add a comment to a highlighted portion of text, or to a area of text that is proceeding the cursor, Orca does not interact with the comment field. Arrowing through the text typed out provides no speech output. Deleting text does not provide speech output.
Activating the menu item under Insert, Comment, yields the same result.
Using the Control + Alt + Page Up and Page Down functions to cycle through comments only reads the text written out for that particular area that is commented, does not allow navigation to the actual comment itself with orca.
Perhaps provide a keybinding that will get to the list of comments presented should there already be some?
