How do I see help inside Line CLI?

How-toUpdated November 2, 2026

Inside Line: type /help or /?. It lists every slash command, the keyboard shortcuts, and short explanations of models, modes, sub-agents, changes, context, background shells, MCP, hooks, Arabic, files, skills and plugins.
From your shell: line --help shows flags, subcommands and examples. Subcommands have their own help, for example line skill --help.
Typing / shows an autocomplete popup with each command's one-line description.
