Allow jumping to a specific page number in the built-in PDF preview

What feature would you like to see?

Please add a page-number input to the built-in PDF preview in the Codex/ChatGPT desktop app so users can jump directly to a specific page.

Problem

The current PDF preview only provides backward and forward arrows, which move one page at a time. For long PDFs, research papers, technical manuals, or appendices, reaching a specific page requires many repeated clicks.

Proposed behavior

• Display the current page and total page count, for example: 12 / 84.
• Let users click or focus the current-page field, type a page number, and press Enter to jump directly to it.
• Clamp or validate values outside the valid page range.
• Support a keyboard shortcut such as Ctrl+G or Cmd+G for “Go to page.”
• Keep the existing previous/next-page arrows.

Why this matters

Direct page navigation is standard in PDF viewers and is especially important for research workflows where users frequently need to jump to a cited page, appendix, table, or figure.

Platform

Windows desktop app, currently branded ChatGPT (previously Codex).
