Description
Describe the bug
On Windows 11 using WezTerm and PowerShell, pressing Shift+Tab fails to cycle the approval mode (e.g., to /plan). The fallback key F10 also does not work.
Other TUI tools (like Claude Code and Codex) handle Shift+Tab perfectly in the exact same WezTerm panes, indicating a specific sequence parsing issue in Gemini CLI for Windows ConPTY environments.
Environment
- OS: Windows 11
- Terminal: WezTerm (running PowerShell)
- Node version: v22.12.0
- Gemini CLI version: 33.1
Keystroke Logs (Pressing F12)
1. When pressing Shift+Tab:
It seems ConPTY strips the escape sequence and passes it as a raw \t:
ℹ [DEBUG] Raw StdIn: "\t"
ℹ [DEBUG] Keystroke: {"name":"tab","shift":false,"alt":false,"ctrl":false,"cmd":false,"insertable":false,"sequence":"\t"}
2. When pressing F10 (Fallback key):
The sequence \u001b[21~ sent by WezTerm does not trigger the CYCLE_APPROVAL_MODE action:
ℹ [DEBUG] Raw StdIn: "\u001b[21~"
ℹ [DEBUG] Keystroke: {"name":"f10","shift":false,"alt":false,"ctrl":false,"cmd":false,"insertable":false,"sequence":"\u001b[21~"}
Expected Behavior
Either Shift+Tab should correctly cycle the mode, or the F10 sequence \u001b[21~ should be mapped to the CYCLE_APPROVAL_MODE command for WezTerm users on Windows.
