Would you consider rephrasing this action? The word "move" makes me think that if I click it, the comments will be removed from the question/answear. But in fact the comments are just copied.
Personally I have never had an issue with the phrasing. It seems direct and accurate. I have used it before. However, if it is confusing people who speak English as a second language, perhaps it could be a little more explicit with what happens
Please avoid extended discussions in comments. Would you like to create a chat room to continue this discussion?
