Selecting entire documents in the Separation Workspace differs slightly between display modes. Selection of pages and documents persists across display modes.
In all display modes, click Select All Documents to select all documents in the Separation Workspace:
If the Select All Documents option has been selected and a new document is added to Document Separation, the Select All Documents button will become unselected. The newly added document is not selected in the Separation Workspace. Selecting the Select All Documents button again will select all documents, including the newly added document.
When selecting pages, hold Ctrl to select a page without deselecting previously selected pages.
If a page is selected and the Shift key is held while selecting another page, all pages between the two selected pages will be selected.
