	[description]

		This command acts differently depending on whether it is executed in
		command mode or in insert mode.

		In command mode, the help command prints the list of defined
		keybindings. In insert mode, if no argument is given, it prints the
		list of available commands. When called with the name of a command
		as first argument, it prints the description of this command.
