[DOCS] Keybindings docs missing ctrl+u/ctrl+d mode-specific behavior (kill-line vs scroll)

Correction after a full re-verification on 2026-04-01: this issue is still only partially resolved, not resolved. The docs now cover chat-input Ctrl+U and transcript-mode Ctrl+U/Ctrl+D scrolling on separate pages, but the keybindings reference still does not give a single clear mode-scoped explanation and still presents Ctrl+D too broadly as exit-only, so this should remain open.

Checked against the latest docs mirror — this issue is still unresolved as of 2026-04-27.

Verification details:

• keybindings.md mentions ctrl+u only as an example of a binding to unbind (line 27), not as a default readline kill-line action in any action table.
• app:exit (Ctrl+D) is documented as a global action and as a reserved shortcut (hardcoded exit), with no mention of half-page scroll behavior in transcript mode.
• The Transcript actions table (lines 156–162) lists only transcript:toggleShowAll and transcript:exit — no scroll actions.
• The Scroll actions (lines 314–337) are scoped to the Scroll context (fullscreen mode) with scroll:halfPageUp/scroll:halfPageDown shown as (unbound), not bound to ctrl+u/ctrl+d.
• The interactive-mode transcript viewer section (lines 87–96) also omits ctrl+u/ctrl+d scroll shortcuts.
• No documentation anywhere describes mode-specific keybinding behavior for these keys.

Issue Summary

This issue reports that the documentation did not explain the mode-specific behavior of Ctrl+U and Ctrl+D, specifically that Ctrl+U should act as readline kill-line in normal/chat mode while Ctrl+U and Ctrl+D should perform half-page scrolling in transcript mode.

---

Verification Results

Claim 1: Normal/chat mode behavior for Ctrl+U is now documented

Status: RESOLVED

At https://code.claude.com/docs/en/interactive-mode, lines 45-55, the Text editing table documents Ctrl+U as Delete from cursor to line start and adds that it stores deleted text for pasting and can be repeated across lines in multiline input. At the same page, lines 23-30 document Ctrl+D in the General controls table as Exit Claude Code session.

Verdict: The current docs explicitly describe the normal/chat mode behavior that the issue said was missing.

---

Claim 2: Transcript mode scrolling behavior for Ctrl+U and Ctrl+D is now documented

Status: RESOLVED

At https://code.claude.com/docs/en/fullscreen, lines 98-110, the transcript mode navigation table states that transcript mode gains less-style navigation and documents Ctrl+u / Ctrl+d as Scroll half a page.

Verdict: The current docs explicitly document the transcript-mode half-page scrolling behavior for Ctrl+U and Ctrl+D.

---

Claim 3: Mode-specific behavior is now communicated clearly enough for users

Status: RESOLVED

At https://code.claude.com/docs/en/interactive-mode, lines 45-55, Ctrl+U is documented under the Text editing section for prompt input. At https://code.claude.com/docs/en/fullscreen, lines 98-110, Ctrl+u / Ctrl+d are documented specifically under transcript mode navigation. At https://code.claude.com/docs/en/changelog, line 1174, the changelog entry states: Fixed ctrl+u in normal mode scrolling instead of readline kill-line (ctrl+u/ctrl+d half-page scroll moved to transcript mode only).

Verdict: The docs now separate the behaviors by mode and align with the changelog change described in the issue.

Conclusion & Recommendation

Primary Concern: The issue reported that the docs did not explain the mode-specific Ctrl+U and Ctrl+D behaviors between prompt editing and transcript scrolling.

Resolution Status: RESOLVED

Recommendation: CLOSE

The current documentation now covers the prompt-editing behavior in interactive-mode and the transcript scrolling behavior in fullscreen, which addresses the missing mode-specific guidance described in the issue.
