How do I submit a job?

I wrote some JCL in ISPF edit. Now what? Is there a submit button or a command?

On the command line type SUBMIT (or SUB) and hit enter. Or SUB and the member name from outside edit.

Then go find it in SDSF (often option ST or type SDSF from the command line depending on your site).

After submit, note the job id (JOB01234). That is how you find it when fifty people are running stuff.
