Undo experiments gone wrong and restore your sanity with two keystrokes
Introduction
Every developer knows the feeling. You ask Claude to "try a different approach" or "what if we refactored this to use a completely different pattern?" Twenty minutes later, you're staring at a codebase that barely compiles, a conversation that's gone off the rails, and a sinking feeling in your stomach.
In traditional development, we have git to save us. But what about your conversation with Claude? What about all those intermediate states before you committed anything? What about the AI's context that's now polluted with failed experiments?
Enter the Double Esc feature—Claude Code's built-in time machine. With just two quick taps of the Escape key, you can rewind to a clean checkpoint and try again. Your code reverts. Your conversation resets. Your sanity is restored.
The Problem
AI-assisted coding encourages experimentation. "What if we tried this?" becomes a phrase you say dozens of times per session. And that's great—until it isn't.
Here's what typically goes wrong:
The Spiral of Doom:
- You ask Claude to try an alternative implementation
- The new approach has issues, so you ask for fixes
- Each fix introduces new problems
- The codebase is now a Frankenstein's monster
- The conversation context is filled with failed attempts
- Claude's suggestions are getting worse because it's confused by all the noise
The Point of No Return:
Without a rewind feature, your options are limited:
- Manually undo all the changes (tedious and error-prone)
- Start a completely new session (losing all useful context)
- Try to guide Claude back on track (often makes things worse)
- Git reset and lose work you actually wanted to keep
The fundamental issue is that experimentation is inherently risky. And when the cost of failure is high, you experiment less. You take fewer creative risks. You stick with "safe" approaches even when a better solution might be just one wild idea away.
The Solution
Double Esc (Esc Esc) is your escape hatch. It creates automatic checkpoints as you work and lets you jump back to any of them when things go sideways.
How to Use It
When you want to rewind:
- Press
Esctwice quickly (Esc Esc) - Claude Code shows you available checkpoints
- Select how far back you want to go
- Choose what to rewind: conversation, code, or both
That's the entire workflow. Two keystrokes to safety.
What Gets Rewound?
You have granular control over what resets:
Conversation only: Rewinds Claude's context and your chat history, but leaves file changes intact. Useful when the code is fine but the conversation went off-track.
Code only: Reverts file changes but keeps the conversation. Useful when you want Claude to remember what you discussed but try a different implementation.
Both: Complete reset to the checkpoint state. Your nuclear option for when everything needs to go.
Pro Tips
Create explicit checkpoints before risky operations:
Before asking Claude to try something experimental, you can make a mental note of the current state. Double Esc automatically creates checkpoints at natural conversation points.
Use it for A/B testing approaches:
You: "Let's try implementing this with React hooks"
[Claude implements]
[You evaluate - not quite right]
Esc Esc → rewind
You: "Let's try implementing this with a class component instead"
Don't be afraid to experiment:
The existence of Double Esc fundamentally changes how you should work with Claude. Go wild. Try crazy ideas. Ask "what if?" more often. The safety net is always there.
Combine with verbal checkpoints:
Before trying something risky, you might say: "Before we try this alternative approach, let me note that the current implementation in UserAuth.ts is working correctly." This gives you and Claude a clear reference point.
Quick escape for runaway responses:
If Claude starts generating something you don't want, a single Esc stops generation. Double Esc rewinds if it already committed changes.
Real-World Use Case
Let's walk through a realistic scenario:
The Setup:
You're building an authentication system. It's working but feels over-engineered. You ask Claude: "What if we simplified this by removing the middleware layer entirely and handling auth directly in the route handlers?"
The Experiment:
Claude starts refactoring. Files change. The middleware is removed. Route handlers are updated. But now you realize... the middleware was also handling rate limiting, and that logic is now completely gone.
The Old Way:
- Panic
- Try to remember what the middleware did
- Ask Claude to add rate limiting back
- End up with a worse architecture than you started with
- Spend 30 minutes untangling the mess
The Double Esc Way:
Esc Esc
→ Select checkpoint from before the refactor
→ Rewind both conversation and code
Now you're back at the working state. You can try again with a more informed prompt: "What if we simplified this by removing the middleware layer, but first, let's make sure we preserve the rate limiting logic somewhere appropriate?"
Total time lost: 10 seconds.
Conclusion
Double Esc transforms Claude Code from a tool where you're always one bad suggestion away from disaster into a true experimentation playground. It removes the fear of trying new things. It encourages creative exploration. It acknowledges that the path to the best solution often goes through several wrong turns.
The best developers I know aren't the ones who always make the right choice the first time—they're the ones who iterate quickly and course-correct efficiently. Double Esc makes you that developer.
Next time you're about to ask Claude to "try something different," don't hesitate. Go for it. The worst case scenario is now just two keystrokes away from being undone.
Coming up tomorrow in Day 3: We'll explore Extended Thinking—how to make Claude actually think before answering complex questions. Sometimes you need more than a quick response; you need deep reasoning. See you then!

Great read and good hack to be remembered.
