There are several ways to add files to your temporary selection:
- If you'd like to add all files in an album, after selecting the album of your choice, click on the "ACTION" button from the upper bar of the thumbnail grid then click on "Add files in the album to the temporary selection".
- If you'd like to add files scattered among several albums, you can drag them one by one to the temporary selection area, or click on the thumbnail of your choice while holding down the control or SHIFT key.
- If you'd like to add a series of consecutive files to the temporary selection, hold down the control or SHIFT key then use the arrows on your keyboard to select files. Each time a thumbnail is highlighted, it will be added to the selection.
