The Original button and the document preview buttons

The document preview buttons display a document's total size, estimated download time, and file format. The estimated download time is the average amount of time it would take to download all the document's slices and frames on a 56K modem. The 2-Up and 4-Up views display additional information that varies depending on the file type selected.

You can use the Optimize panel to optimize a document while viewing a preview as if you were in Original view. You can optimize the entire document at once or only selected slices. The slice overlay helps you differentiate the slices currently being optimized from the rest of the document. The slice overlay displays areas not currently being optimized with a dimmed, transparent white tint. You can turn the slice overlay on or off.

When you optimize a selected slice, the slices not being optimized are dimmed.
