can't edit comment using shift+f2?

[mSolver]

In office 365, there's this new function that looks exactly like the comment function but it's not.

Is there a keyboard shortcut to edit the comments for this type? Usually shift+f2 works but not for this:

I'm trying to find a way to do it with keyboard shortcut.

If you are editing Threaded Comments frequently enough to need a shortcut key, I suspect you should be Notes and not Comments.
As I said in the previous post, I think editing anything other than the very latest post is potentially really misleading.
You can possibly set up a macro and assign a shortcut key to that but you would have to tell it which message in the chain you want to want to edit.
That is probably why Ctrl+Shift+F2 can't take you straight to edit mode since it takes you to the point at which you need to either reply OR to "select which message" you want to edit.
