Displaying Line Numbers
By default, line numbers are switched off in the Source Editor to save space and reduce visual clutter. If you need the line numbers, you can turn them on by choosing View | Show Line Numbers. You can also right-click in the left margin of the Source Editor and choose Show Line Numbers.
