About one hour ago Google announced a couple of new file preview options for Google Drive users. Now you can quickly visually flip through files in your Google Drive account just by tapping the left and right arrow keys on your keyboard. There are a couple of ways that you can access the new preview option. If you right-click on the name of a document or file you can select “preview.” The preview option automatically appears if you click on the name of a PDF, image, or video. Either way, once the preview pane is open you can quickly flip through visual previews of all of your files.
This feature has not been rolled out to all Google Drive users yet. It will be rolled out over the course of a few days.
