By job, are you referring to a task within a Schedule or an instance when the Schedule will run (at which time it would run one task after another)?
If what you're looking for is a way to temporarily disable a Schedule, you can retire it for a bit and then unretire it later in the day. Right click on the schedule and click Retire. It will move into the next group down for Retired Schedules. This will 'disable' the entire Schedule though, so none of the tasks within it would run. And once you unretire it (that is, re-enable it), the Schedule will not run immediately. You'd have to either right click and hit 'Run Now' or make sure that one of its scheduled times will come up during the remaining portion of the day.
