3434| `Ctrl+Enter` or `Ctrl+X Ctrl+S` | Send queued messages now | Interrupts the current turn so your [queued messages](#queue-messages-while-claude-works), and your draft with them, go out right away instead of when the turn ends. In [shell mode](#shell-mode-with-prefix), the key queues your command without interrupting. In terminals that don't report extended keys, `Ctrl+Enter` arrives as plain `Enter`; `Ctrl+X Ctrl+S` works in any terminal. Requires Claude Code v2.1.275 or later |
3535| `Shift+Tab`, or `Alt+M` on Windows when the Node or Bun runtime doesn't enable VT input mode | Cycle permission modes | Cycle through `default` (labeled Manual in the mode indicator), `acceptEdits`, `plan`, and, when available, `bypassPermissions` and then `auto`. From `auto`, the first press switches to `default`. See [permission modes](/docs/en/permission-modes). On a file permission prompt, the same key closes an open [comment field](/docs/en/permissions#add-a-comment-when-you-answer-a-permission-prompt). With no field open, it selects the option that allows the action for the rest of the session, when the prompt offers that option |
3636| `Option+P` (macOS) or `Alt+P` (Windows/Linux) | Switch model | Switch models without clearing your prompt |
37| `Option+T` (macOS) or `Alt+T` (Windows/Linux) | Toggle extended thinking | Enable or disable extended thinking mode. Has no effect on Fable 5.1 or Fable 5, which always use extended thinking. Works on macOS without configuring Option as Meta |
37| `Option+T` (macOS) or `Alt+T` (Windows/Linux) | Toggle extended thinking | Enable or disable extended thinking mode. Has no effect on Opus 5.5 or the Fable models, which always use extended thinking. Works on macOS without configuring Option as Meta |
3838| `Option+O` (macOS) or `Alt+O` (Windows/Linux) | Toggle fast mode | Enable or disable [fast mode](/docs/en/fast-mode) |
