Selecting a document previews it beside the list, so you can scan a client's file without opening and closing pages. The documents list with a client group expanded and a bank statement previewed in the pane on the right. ## Open a preview * **Single-click** a document row to preview it. * **Double-click** it to open the full document page. * With the tree focused: **↑** and **↓** move, **→** and **←** expand and collapse a group, **Enter** previews the highlighted document, **Home** and **End** jump to the ends. Preview supports **PDF**, **TIFF**, **Excel** (`.xlsx`), and **Word** (`.docx`). ## Viewer controls Along the top of the preview: a thumbnail and outline menu, page navigation with the page count, a pan tool, and zoom in and out. ## Arrange the panes The workspace has three panes: **list**, **preview**, and **details**. Toggle each one from the control in the header. The three pane toggles in the documents header, with list and preview switched on. All three panes on: the document tree, the PDF preview, and the details pane showing the Attributes tab. `⌘\` (`Ctrl+\`) cycles the three common layouts: all panes, list and preview, list only. Drag the dividers to resize; Denari remembers your split. ## What is in the details pane The right pane holds everything about the selected document: [Attributes](/documents/attributes), [Versions](/documents/versioning), **History** (an audit log of who viewed, edited, locked, or commented, and when), and **Comments**.
