You can do everything. You can "trace into", "step over", "next instruction", "run to breakpoint", or "run". All these actions are in your Debug menu, all these actions have their hotkeys, all these hotkeys can be changed in the Settings menu.
Unlike most of "normal" debuggers, there is no "default breakpoint" at the beginning of your app. On starting a debugger, the app will run until it finds one. If it finds none, it will run until it terminates or crashes. Therefore, you always need to set some breakpoint before starting a debugger. Then you can debug your app line by line, set another breakpoint elsewhere and run to it, or do something different.
