Appearance

Transcript display ​

Parent: Interactive TUI.

The interactive TUI owns the transcript viewport while it is open. Scroll with the built-in controls, not the terminal's scrollback. When you exit, your previous shell view returns. If a session exists, Rho prints only a short saved-session summary.

Scroll and follow ​

ControlAction
pageup / pagedownScroll the transcript viewport
Mouse wheelScroll the transcript viewport
ctrl-end (default)Jump back to the live bottom
Left-click and dragSelect text; copy on release

The jump binding is keybindings.jump_to_bottom in config (default ctrl+end). It must differ from open_editor. Restart Rho after keybinding changes.

Live bottom vs manual scroll ​

  • Following the bottom: transcript content stops one row above the spinner so the activity rail stays clear.
  • Scrolled up: the full last visible row stays drawn wherever the spinner and jump control are not painted.
  • Away from the bottom: Rho overlays a right-aligned control such as ↓ jump to bottom ctrl+end on the last transcript row. Only that control's cells are covered.
  • During generation: the spinner is similarly overlaid on the left.

Press the jump binding or click the button to resume following live output.

Markdown and structure ​

Assistant Markdown renders in the feed as it streams.

FeatureBehavior
ATX headings # … ######Syntax markers are dropped. Each level has its own color. H1–H3 use stronger emphasis
Code fencesBordered blocks with a top-right COPY control that highlights on hover
Mermaid fencesTerminal diagram art when supported; see Mermaid diagrams
Display and inline mathTXM Unicode art for closed $$...$$ and single-row $...$; see Math rendering
Tables and ordinary MarkdownWrapped to the pane width

Heading-like text inside code fences, or invalid heading lines, stays literal.

Copy ​

  • Drag-select transcript text to copy it to the terminal clipboard. Rho briefly shows how many characters were copied.
  • Code block, Mermaid, and math panel COPY actions sit in the top-right border and highlight on hover. For Mermaid and math, COPY always copies the source, not the rendered art.
  • Click without drag does not copy. The code-block copy control is excluded from drag selection so a click on COPY does not grab neighboring text.

Stream idle timeout ​

Provider streams that deliver no meaningful payload for two minutes are treated as stale. Keep-alives such as SSE pings do not reset that timer. Rho can then surface a stream-idle error and leave the stuck working state instead of waiting forever.

Connection setup uses its own connect timeout. Non-streaming HTTP requests are not bound by the two-minute stream idle rule.

Display modes ​

zen_mode (under /config → Models & reasoning) hides tool cards, reasoning blocks, and the Thinking... placeholder so the transcript shows message text. The live activity rail and subagent rows stay visible. Tools and reasoning still run; only their transcript display is suppressed. The setting applies immediately, including during the current turn.

Exit ​

Leaving the TUI restores the prior shell view. Session data stays on disk under the sessions layout. Export a transcript with /export or rho sessions export.
