I am trying to Copy/Paste within Math Mode and it just pastes raw TeX code in the text area. I have looked at https://tex.stackexchange.com/questions/80133/copy-and-paste-of-mathematical-formulas-pastes-the-unformatted-raw-tex and still cannot get it to work. I am using LyX 2.2.2 on Mac OS X 10.7.5.
