1. PRESSING ALT then V and then A brings you to a thumbnail display, called page sorter view, of all pages contained within the open file you're working with. You can also navigate under the menu to VIEW | PAGE SORTER VIEW. The pick tool is the only tool available in this view. You can re-order pages using this view by dragging the thumbnails around. Right click a certain page to delete, insert or rename them. There is an exit page sorter view button in the top main button area which will exit this mode.
2. If you have more than one file open, HOLDING down CTRL while pressing the TAB key allows you to toggle through the open files to select which file that is currently being used. You are able to drag objects from either of the open files and drop them into another open file you wish them to be placed in.
