Description
The Tab key toggle for extended thinking mode is not working. Once thinking mode is enabled, it cannot be disabled via Tab key, even after:
- Restarting Claude Code multiple times (5+ times)
- Rebooting the computer
- Switching models (Opus 4.5 → Sonnet → Opus 4.5)
Environment
- Claude Code version: 2.0.67
- Platform: macOS (Darwin 25.1.0)
- Terminal: Default macOS Terminal
Configuration checked
All settings are correct:
MAX_THINKING_TOKENS: Not set (empty)~/.claude/settings.json: "alwaysThinkingEnabled": false~/.claude/settings.local.json: No thinking-related settings- Shell profiles (~/.zshrc, ~/.bashrc, etc.): No THINKING environment variables
Expected behavior
Pressing Tab key should toggle thinking mode on/off as documented in:
Actual behavior
- Tab key does not toggle thinking mode
- Thinking mode remains enabled regardless of Tab key presses
- Session logs show
"thinkingMetadata":{"level":"high","disabled":false,"triggers":[]}
Steps to reproduce
- Start Claude Code
- Enable thinking mode (via Tab or by typing "think")
- Try to disable thinking mode by pressing Tab
- Observe that thinking mode remains enabled
Additional context
- The
? help menu shows other keyboard shortcuts (Shift+Tab, Option+Enter) but Tab toggle doesn't respond
- This issue persists across new sessions and computer reboots
