I'm sure you know how to select a photo in Photoshop Elements Photo Organizer... just click it in the photo well. Selected items will have a blue border around them. To select multiple items that are together you can click the first item, then Shift-click on the last item you want to select and you'll also get everything in between the two. If the items are separated, you can click on the first item, and Ctrl-click additional items. To select all items shown in the photo well, use the shortcut Ctrl-A or go to Edit > Select All.
When you are in Folder view or Import Batch View, there are two additional ways to select a group of items. The photo well will display divider bars separating the groups of pictures. In Import Batch View the bar will show the text "Imported from ___ on ___" and in folder view it will show the path to the files on your computer. Simply click the divider bar to select the entire group!
This tip also applies to Adobe Photoshop Album and the free Adobe Photoshop Album Starter Edition.
