With the Jobs (dbms_job) tab in the SB, you can easily highlight and copy all/part of the "what" of a job from the lower RHS.
With the Sched. Jobs (dbms_scheduler) tab in the SB, the Job Action text visible when the Info tab is active cannot be copied. You have to go to the Script tab, but even then the text will have all single quotes replaced with double single quotes. So, if you want something, you have to navigate to another tab, highlight a very specific section, and then run it through a replace to convert the quotes.
It would be great to make the Job Action text (which is formatted correctly with single quotes) available for easy selective copying on the Info tab.
