If you have used the Group step to create a group containing several steps, when debugging, a breakpoint can be created at a Group step in the same way as when creating a breakpoint at any other step. If the group is collapsed, however, using single-stepping will treat the group as a single step and not enter any of the grouped steps. If the group is expanded, the steps in the group will be visited when using single-stepping. If a group is collapsed, using the icon, instead of the icon, it will result in the debugger stepping-into the group and visiting each step. If you wish to leave the group and advance the debugger to the step following the Group step, you can use the icon to step out.
