In Normal mode, Tab/Shift+Tab cycles focus between Files and the visible text panes, skipping absent panes. Switching Before/After synchronizes the primary cursor by aligned diff row and display column. A missing counterpart uses the nearest visible source row; shorter lines clamp the column while retaining the preferred display column for the return trip. Vertical wheel input scrolls the visible panes without moving the focused text caret; switching sides by vertical wheel also synchronizes the cursor. Over Files it navigates visible tree rows without opening them. Horizontal wheel input in either split synchronizes the Before/After horizontal offsets, bounded by the longer side, without changing focus, cursor, or selections; over Files it is consumed. Added/deleted files retain single-pane scrolling. While a comparison is open, Escape cancels modes, prompts, or filtering, or returns picker focus to the last bound text pane; it leaves the comparison open. Use **`:diff.close`**, find `diff.close` in the palette, or bind **`config.core.diff.close`** to leave the comparison explicitly. The dotted command is intentional; there is no `:diffclose` alias.
Both diff panes apply available semantic tokens from their own buffer, independently of keyboard focus. Historical snapshots never borrow the working buffer's tokens; live After tokens must match the displayed text revision. Missing or invalidated tokens leave Tree-sitter syntax colors intact. Semantic colors and modifiers preserve the change backgrounds.
Both diff panes apply available semantic tokens from their own buffer, independently of keyboard focus. Historical snapshots never borrow the working buffer's tokens. Typing and undo/redo retain semantic colors outside the edited range, shifting their positions to follow the text until a current LSP reply replaces them. Edited ranges fall back to Tree-sitter syntax colors while waiting; semantic roles elsewhere can briefly lag changes. Semantic colors and modifiers preserve the change backgrounds.
Binary data, missing final newlines, permission/type changes, symlink targets, and submodule pointers have explicit notices. Symlinks are not followed and submodule contents are not traversed. jj conflicts use jj's file-content projection and carry conflict notices; ordinary files remain readable. Identical-content moves are shown as renames; modified moves appear as an added and removed file.

Markdown heading markers (`#` through `######`, or Setext underlines) share the heading text's markup color. List markers (`-`, `+`, `*`, and ordered prefixes such as `1.` or `1)`) also use cyan markup, including nested and blockquoted lists. Plain-text hashes and other punctuation keep their existing styling.
An enabled supporting LSP server supplies semantic tokens automatically, overriding syntax colors only on recognized spans. Semantic colors also use the terminal palette: namespaces neutral gray, types cyan, variables/parameters light cyan, and properties blue. Readonly variables/parameters/properties keep those role colors and add italics; declarations/definitions are bold, documentation comments italic, and deprecated symbols struck through. Italic emphasis depends on terminal support. Tree-sitter fills gaps and remains available while new tokens are pending after edits. Search, Visual selections, diagnostics, and carets keep their existing precedence. See [native LSP configuration](configuration.md#native-lsp) for provider support and server-stack routing.
