With this function you can move one or more frames directly to the current master page without having to use the clipboard to cut and paste. This function works in both directions, of course: If you are working in the master page mode and click on this icon, frames that are selected on the current master page will be moved to the layout page that was active before you changed to the master page mode. Generally the frames will be placed on a level above all frames that may be present already, no matter which level they lay in previously.
