If you wish to execute several statements without repeatedly clicking the Step Over debugger command, you can right click the statement where you’d like to continue step-by-step execution, then select Run to Cursor from the menu that appears. The debugger will execute the statements up to, and including, that statement. 5. When an app is running in the debugger, the Start Debugging command becomes the Continue command. If you click Continue while in break mode, the debugger will execute statements until it reaches the next breakpoint. If there aren’t any, the program will simply execute until it completes or until the event handler that you’re debugging finishes executing.
