claude-code - 💡(How to fix) Fix [FEATURE] Single-key model cycling keybinding (re-file of #38966) [2 comments, 2 participants]

Preflight Checklist

• I have searched existing requests and this feature hasn't been requested yet
• This is a single feature request (not multiple features)

Problem Statement

There is no way to bind a single keystroke that cycles the active model, analogous to how Shift+Tab cycles permission modes via the chat:cycleMode action. Existing options all break flow:

• Alt+P / Ctrl+Y opens the model picker — a menu that must be visually scanned and dismissed.
• /model only works from an empty prompt.
• The only model-related keybinding actions exposed today are chat:modelPicker, modelPicker:decreaseEffort, modelPicker:increaseEffort, and modelPicker:setAsDefault. None of them cycle models from the chat input in a single keypress.

This is a re-file of #38966, which was auto-closed by the stale-bot on 2026-05-06 with "Please open a new issue if this is still relevant." It is still relevant.

Proposed Solution

Add a chat:cycleModel action (bindable from the Chat context) that rotates through a user-configured list of pinned models on each keypress and wraps around.

Configuration (settings.json):

```json { "modelCycle": ["opus", "sonnet", "haiku"] } ```

Keybinding (keybindings.json):

```json { "context": "Chat", "bindings": { "alt+m": "chat:cycleModel" } } ```

The active model is already shown in the status line, so visual feedback is in place.

Alternative Solutions

• chat:modelPicker (existing) — opens a picker; not a one-keystroke cycle.
• /model <name> slash command — requires typing and an empty prompt.
• UserPromptSubmit hooks triggering on trigger words — clever workaround but not a keybinding.

Priority

Medium - Workflow improvement

Feature Category

Interactive mode (TUI)

Use Case Example

Mid-session model switching is common: Sonnet for implementation, Opus for tricky design calls, Haiku for quick lookups. Shift+Tab already gives this UX for modes; models deserve the same.
