Hello again,
It seems that we cannot use the ctrl+c key combo to copy a section of code in the Styles window. I can copy single selectors or declarations and use them this way, but not say an entire CSS rule or part of the CSS page.
I can, however, use the App's System Menu choosing the Edit and then in the drop down choose Copy. I can highlight anything I want in the Styles window then and it will copy it, doesn't matter if it's one rule or the entire page. I can then use the ctrl+v to paste it and it works.
So basically the key combo to copy doesn't work in the Styles part of the editor.
