Keyboard shortcut or setting to expand [Pasted text #N] placeholders inline

Preflight Checklist

• [x] This is a single feature request (not multiple features)

Problem Statement

When pasting multi-line or longer text into Claude Code's input, it automatically replaces the content with a placeholder like [Pasted text #1]. While this keeps the UI clean, it prevents editing the pasted content before submission, which breaks workflows that rely on reviewing/editing auto-generated prompts.

Current Workarounds

1. Submit + ESC ESC: Press submit, then quickly press ESC twice to cancel and see the text

• Problem: Uncomfortable, hacky, requires quick timing

1. Paste into external editor first: Edit there, copy back

• Problem: Breaks the auto-paste workflow, adds friction

Steps to Reproduce

1. Copy text with multiple paragraphs (~500+ characters)
2. Paste into Claude Code input
3. Observe: Shows [Pasted text #1] instead of actual text
4. Cannot edit content without submitting first

Environment

• OS: Windows
• Terminal: VS Code integrated terminal
• Claude Code version: v2.0.33

Proposed Solution

Option 1: Keyboard shortcut (preferred)

• Add shortcut (e.g., Ctrl+Shift+E or V or click on placeholder) to expand inline
• Allows editing while keeping clean UI for those who don't need it

Alternative Solutions

Option 2: Configurable threshold

• Setting like paste_inline_threshold: 1000 (characters)
• Text below threshold pastes inline, above uses placeholder

Option 3: Always expandable

• Make [Pasted text #N] clickable to expand/collapse
• Best of both worlds: clean UI + editability

Use Case Example

I have a voice recording application that:

1. Records audio instructions in my native language
2. Transcribes using Whisper API
3. Translates and formats the text
4. Auto-pastes into Claude Code

For recordings of 2-3 minutes (~500-1000 characters), the text appears as [Pasted text #1] instead of inline. This means I cannot review or edit the auto-generated prompt before sending it, which is essential for catching transcription errors or refining instructions.

Additional Context

The current behavior works well for very large pastes, but for medium-length content (500-1500 characters) that users often need to edit, having no way to expand the placeholder is limiting. This particularly affects automated workflows where prompts are generated programmatically.
