It seems to me that this would be a simple addition and would be very helpful in correcting a simple spelling error, etc.

Did you intend to submit this as an Idea? We cannot Vote or comment on on this suggestion as a Document.

I'd like to but I can't navigate to the right tab. How 'bout a clue?

did you find it yet?  if so you should include a link to the product idea.  If not here is a link to where you can create the idea:

I will vote for this idea as it would be useful feature for both comments in the version history, as well as editing approval comments as part of Change Management.
