Claude Code has a lot of small interface commands that are easy to miss, but they make long sessions much more comfortable.

The biggest one is /voice. It turns on voice dictation in the CLI, with hold mode or tap mode. It requires a Claude.ai login and a local microphone, because the audio is transcribed by Anthropic rather than processed locally. It is useful for long prompts, accessibility, and live coding when speaking is faster than typing.

There are also display and terminal commands. /focus reduces visual noise so you see the current prompt, a tool summary, and the final response. /theme changes the color theme. /statusline configures the prompt status line. /tui switches between the default and fullscreen terminal renderers. /keybindings lets you customize shortcuts, including the voice push-to-talk key.

None of these changes how Claude reasons, but they change how usable the tool feels when you are inside it all day.
