While exploring Claude Code’s /terminal-setup command (found via a /sta fuzzy search in v1.0.111), I noticed the default Shift+Enter binding for terminal input inserts an unwanted backslash before the newline.
Claude Code currently drops its keybinding into the standard VS Code profile (for example, ~/Library/Application Support/Code/User/keybindings.json on macOS). I spend most of my time in VS Code Insiders, so I copied the entry into ~/Library/Application Support/Code - Insiders/User/keybindings.json to make the shortcut available there, too.
