As with other shells, you can start a job in the background by putting "&" at the end of the command. Or, having run a job in the foreground, you can suspend it by pressing Control-Z.
The command "fg <N>" puts a job in the foreground. <N> is a job number; it is not prefixed with a "%", unlike in Bash.
The command "bg <N>" resumes a job in the background.
There is no command for listing the currently active jobs yet.
