Looks like it. :-)

Yes:
% jobs
[1] Suspended gv aaaa.ps
[2] Suspended xpdf /tmp/w3dzz-antenna-iss-1-31.pdf
[3] - Suspended xpdf /tmp/robe.pdf
[4] + Suspended xpdf /tmp/anwenderaspekte_svm_3.3.pdf
% fg 3
xpdf /tmp/anwenderaspekte_svm_3.3.pdf
But using the correct syntax, this happens (as expected):
% fg %3
xpdf /tmp/robe.pdf
Explanation from "man csh":
There are several ways to refer to jobs in the shell. The character
`%' introduces a job name. 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 fore-
ground. Similarly, saying `%1 &' resumes job 1 in the background, just
like `bg %1'. A job can also be named by an unambiguous prefix of the
string typed in to start it: `%ex' would normally restart a suspended
ex(1) job, if there were only one suspended job whose name began with
the string `ex'. It is also possible to say `%?string' to specify a
job whose text contains string, if there is only one such job.
[...]
fg [%job ...]
Brings the specified jobs (or, without arguments, the current
job) into the foreground, continuing each if it is stopped.
job may be a number, a string, `', `%', `+' or `-' as described
under Jobs. See also the run-fg-editor editor command.
So the command
> fg %3
^
will probably do what you want. :-)
