Stepping through regions of a file with the rest dimmed.

For AI Agents

Hand your agent this brief or the ReUI MCP, not a screenshot. Free to install.

Best for: A 3 step tour of a checkout function, chosen with pressed buttons in the header, with a step counter and the other lines dimmed

When to use

Assistant replies and agent output that stream code, or lines a reader picks to ask about
Code review of diffs, git patches and diagnostics, with accept, reject and fix actions
Docs snippets and terminal or test logs with line numbers, copy, wrap, folding and search

When not to use

Emphasis on a few lines while the rest stays at full strength: use the Code Block Highlights example
A full assistant conversation screen with thread list, transcript and composer: use the AI Chat blocks
A discount or promo code shown for a shopper to copy at checkout: use the Coupon blocks
A release console with environment lanes, a deploy history grid and streaming logs: use the Dev Ops blocks

Agent notes

Each steps entry pairs a button label with a lines range for this sample; rewrite both for your own file
Line specs such as highlightedLines, diff and folded count source lines from 1, whatever startLine prints in the gutter
maxLines caps height only on the built-in surface; with CodeBlockContent inside your own ScrollArea, cap that viewport yourself
Hoist transformers to module scope; a new array on every render re-tokenizes the whole file
