Take Command of ChatGPT

ChatGPT has no secret codes. It has something better: real commands most people never find.

ChatGPT changed more in 2026 than in the two years before. There's a new desktop app with a real slash-command menu, GPT-6 models, an agent called Work, a standalone Deep Research tool, and a list of retired features that most cheat sheets still teach. This field manual shows you what actually works today, step by step.

Inside you'll find:
• The 15 moves every user should know, from the one shortcut that lists all the others to plain-English memory commands
• Every real keyboard shortcut and slash command, and the viral "secret codes" (DAN, "God mode", "developer mode") that are myths
• Step-by-step walk-throughs for Work, Projects, Space, Deep Research, custom instructions, scheduled tasks, voice, images, file analysis and study mode
• The 6-part prompt formula and 26 copy-ready templates, plus five before-and-after prompt makeovers
• Playbooks for six roles: IT administrator, security analyst, small-business owner, marketer, student or teacher, and manager
• A 7-step verification workflow, a troubleshooting table and a team adoption checklist
• The privacy and security settings that matter, and real incidents from 2025–2026
• Three quick-reference cards and a 24-term glossary
