In Word (version 14 from Office 2010), when I'm editing a review comment (text that appears in the right margin in the user interface), I want the keyboard shortcuts Ctrl+Home and Ctrl+End to move to the beginning and end of the comment, and not to the beginning and end of the document.
I know how to change keyboard shortcuts, that's not the question. What do I need to bind the keys to? I'm guessing I'd have to write a macro. How do I detect whether the cursor is in a comment or not? When in a comment, how do I move to the beginning/end of the comment?
