I need to be able to select all content on a page and move it all down. Ultimate goal is to add new content to top of page below heading, but need space available. Only way I can think to do that is to select all and move content. But I can't. Even though time consuming, I also can't ctrl-click on each item and move all down. Once I get to bottom of screen, if I try to scroll down to select more, it de-selects what I've already chosen.
There's another thread that suggests using the Settings in Background Tools to change width or height, but those changes affects ALL pages. That's not really a solution.
