I need to change two lines in %permissionLevels = (); like this
# become_student => "ta",
# score_sets => "ta",
but I do not want to add the whole %permissionLevels = (); which is many lines, to course.config, at a linux linux terminal, typing one line at a time, just to change 2 values. I want to add those two lines to course.config using Webwork editor. Copy paste the lines or the whole %permissionLevels = (); into Webwork editor does not work, it corrupts the file, so I have to type those 2 lines by hand, in the Webwork editor.
What is the syntax to add just those two lines, keep the rest of permission levels unchanged (as it is defined somewhere in Webwork)?
