/diff

Opens an interactive diff viewer for uncommitted changes and turn-by-turn diffs.

/diff opens an interactive diff viewer for the current working state. The left/right arrow keys switch the view between the Git diff of uncommitted changes and the individual turn-by-turn diffs of the conversation; up/down browses through the changed files. Enter opens the diff of the selected file; inside it you scroll with the arrow keys, PageUp/PageDown, j/k, Space, or Home/End, and Esc returns to the file list. Since version 2.1.198, the open viewer automatically updates when the repository's Git state changes outside the session, for example through a branch switch or commit in another terminal. /diff shows only uncommitted changes and conversation turns, not history across multiple commits, and it does not evaluate the content of the changes. To reset to an earlier state, use /rewind instead, which rewinds code and conversation together.
