The timeline command fetches a timeline (home, local or federated).

The timeline "direct" contains only direct messages (that is, messages with

visibility set to "direct").

It can also get a hashtag-based timeline if the keyword or prefixed with

':' or '#', or a list-based timeline (use !ID with the list ID).`,

	Example: `  madonctl timeline

  madonctl timeline public --local

  madonctl timeline '!42'

  madonctl timeline :mastodon

  madonctl timeline direct`,

	RunE:      timelineRunE,

	ValidArgs: []string{"home", "public", "direct"},
