What it does

Codex-style auto-hiding right-edge turn rail: edge-peek show/hide, per-turn tooltip, in-rail search, and a scrolling 30-turn window for long sessions.

Best for

  • Users navigating long DSH Web conversations who need quick per-turn previews and jumps.
  • Sessions where searching user messages is faster than manually scrolling through the transcript.
  • Users who prefer an unobtrusive, auto-hiding navigation aid with no settings or model impact.

Not ideal for

  • Short conversations where ordinary scrolling already provides sufficient navigation.
  • Non-Web profiles or Web profiles without the required sessionProjections service.
  • Users needing more than 30 markers visible at once; longer sessions use an internally scrolling 30-marker window.

README

dsh-turn-rail

A Codex-style auto-hiding turn rail for DeepSeek Harness Web.

Minimal by design: no settings, no extra panels, zero runtime dependencies.

The rail lives on the right edge of the conversation. Move the pointer near the edge and it fades in; move away and it fades out. Hover the thin zone around a marker to preview that turn, click anywhere in the wider marker area to jump. Long conversations keep at most 30 visible markers and scroll inside the rail, following the current reading position.

This project is not affiliated with DeepSeek. The interaction pattern is inspired by common turn-navigation rails such as Codex and the DeepSeek web client; the implementation is independent.

Tooltip and search

Features

  • Edge-peek auto-hide — appears when the pointer is within 110 px of the right edge, fades out 120 ms after leaving. Leaving the browser window or switching away follows the same fade timing.
  • Layered hit zones — the outer zone only keeps the rail visible; the marker zone is clickable and highlights on hover; only the narrow detail zone around the marker shows the tooltip.
  • Per-turn tooltip — one marker previews one message with time. It fades in and fades out with the rail, and the native browser title is not used.
  • Search — the magnifier button opens a pinned search box. Type to filter user messages, click a result to jump. Close with Esc, another click on the button, a result click, or a click outside the rail.
  • 30-marker scrolling window — with more than 30 turns the rail scrolls internally with a hidden scrollbar. It pins to the newest window once when a session opens, then never moves itself again: the rail scroll position is fully user-owned.
  • Theme-aware and responsive — markers use DSH CSS variables and scale slightly with viewport size.
  • Full-session projection — the host half folds the durable session log so a page reload paints the complete rail without replaying history.

Requirements

  • DSH >= 0.1.0-rc.6
  • Web profile with sessionProjections available (the shipped web profile has it)

Install

dsh plugin --profile web add dsh-turn-rail

Then restart dsh web and hard-refresh the browser tab.

Remove
dsh plugin --profile web remove dsh-turn-rail

Tuning

All tunables live at the top of lib/client.js:

Constant Default Meaning
EDGE_TRIGGER_PX 110 Show the rail when the pointer is this close to the right edge
DETAIL_LEFT_PX / DETAIL_RIGHT_PX 46 / 10 Distance band from the right edge that opens the tooltip
HIDE_DELAY_MS 120 Wait before the rail starts fading out
UNMOUNT_AFTER_MS 200 Remove tooltip/search after the fade completes
MAX_VISIBLE_MARKS 30 Maximum markers visible when the rail scrolls
MAX_MARK_GAP_PX 30 Maximum center-to-center distance between markers when there are 30 or fewer turns
SEARCH_LIMIT 30 Maximum search results

Rail geometry and marker sizes are in the css array in the same file.

Model Experience

None. This is a browser UI plugin; nothing here enters a model request.
