I don't think they are duplicates coz both of them asked different questions about remapping different keys and my answer seems to be applicable to both of them
@Ajay I agree that they are not exact duplicates, so yeah, go ahead and post an answer. Make sure to adjust it properly to answer OP's question, don't just copy-paste it. Also I would suggest adding the installation instructions explicitly to both answers, instead of providing a link that provides a link for that, and add instructions for how to add the program to startup applications too.
@Ajay Very nice! I also did some edits, which I think improve your answer to the old post a bit. Feel free to edit them further if you feel so or incorporate them to your answer in the new post if you like them! +2 for you!
BTW, the OP here wants to make the mic key a backspace key, not a Ctrl+C, so I think you have to change the relevant screenshot. You may add the Ctrl+C screenshot to the other answer.
@BeastOfCaerbannog the questions may not be dupes, but the answers are, so it still makes sense to close. The point of closing as a duplicate is to avoid repeating information, so if the solution is basically copy pasting the other answer, better to close as dupes.
