I'm very sorry for the confusing title. Please edit it if you can find a better way to express the question. So, the basic idea is that Person 1 is the OP, and Person 2 is the answerer. Let's say the question is:
How do I open Terminal Quickly?
I have been looking for an easy way or short-cut to open the Terminal quickly, so I don't have to find it in the Dash.
And the answerer answers:
You can open Terminal easily by finding it in the Dash, or you can pin it to the Unity sidebar. Both are quick and easy to use.
However, Person 1 says in the comments of that answer:
Is there a way to use the keyboard to initiate the Terminal?
And the answerer then replies,
Yes, you are able to use Ctrl + Alt + T on your keyboard as a short-cut.
So technically, the answerer answered the question, but in the comment and not in the actual answer. Does that make the answer the right one? And should the OP detonate in the comments of the answer that the comment was the correct solution? Delete this question if you wish, I was just wondering and thought it was a bit odd.
