 3. **Diff**: the editor expands to full screen, covering the other columns. The original file is on the left and the updated file is on the right, lines aligned. `Esc`, or a collapse control in the corner, returns to the normal layout and the previously active mode.
 4. **Preview**: markdown files only. It shows the rendered document instead of the source.

-**In Actual, the removed lines appear on a click.** The user clicks a marked line, and a panel opens over the agent and terminal column: 496px wide, with a 2px amber-deep left border. The panel holds the whole original file, and it scrolls so that the previous version of the picked line sits level with the picked line. A second click on the same line closes the panel, and so does a click anywhere off the code. Hover does nothing, and there is no animation.
+**In Actual, a click on a marked line opens the Diff.** The full-screen side-by-side view comes up on the pair of the whole file, HEAD against disk, and both panes scroll so that the clicked line sits in the middle of the window. A line near the start or the end of the file goes as near to the middle as the file permits. `Esc` returns to Actual. Hover does nothing, and there is no animation.

 Shared rules: teal is what the file holds now, amber-deep is what it held before. There is no green and no red anywhere. Syntax highlighting stays on in all modes. Line numbers follow `editor.lineNumbers` (default absolute).
