According to bcherny on X, developers can streamline Claude Code terminal usage by configuring four key features: theme selection via /config, notifications through iTerm2 or a custom hook, Shift+Enter newlines enablement with /terminal-setup for IDE terminals including Apple Terminal, Warp, and Alacritty, and Vim keybindings via /vim; as reported by the Claude Code docs, these commands improve productivity by reducing context switching and input friction in AI-assisted coding sessions (source: Boris Cherny on X; Claude Code documentation at code.claude.com/docs/en/terminal-config).
