jobs
http://www.unix.org.il/tcsh/Jobs.html
If you are running a job and wish to do something else you may hit the suspend key (usually ^Z) which sends a STOP signal to the current job. The shell will then normally indicate that the job has been ‘Suspended’ and print another prompt.
You can put it in the “background” with the bg command or run some other commands and eventually bring the job back into the “foreground” with fg.
If you wish to refer to job number 1, you can name it as %1. Just naming a job brings it to the foreground; thus %1 is a synonym for fg %1, bringing job 1 back into the foreground. Similarly, saying %1 & resumes job 1 in the background, just like bg %1.
The shell maintains a notion of the current and previous jobs. In output pertaining to jobs, the current job is marked with a + and the previous job with a -.

screen
if jobs ain't doin’ it. Type screen - gives a new ‘session’ -- start whatever you want in here. Then simply close the ssh session. Restart another ssh session and then do a ps. You'll see p0 with the current stuff, plus p1 with the screen session. To bring the other screen session to the front, use
screen -D -R
To stop that screen session, simply type exit. Sorta like su.
screen -- start a NEW screen session
screen -r -d -- pick up a preexisting screen session
screen -ls -- list screen sessions without doing anything
screen -r -d [number] -- pick up screen session [number]
