 * of a step/into or step/over), the debugger changes focus to most deeply
 * nested function in the call stack (because that's the function that's
 * executing).
 *
 * You can change the debugger focus to other stack frames - once you do
 * that, you can examine the source code for that frame, the variable values
 * in that frame, and the breakpoints in that target.
 *
 * The debugger focus remains on the selected frame until you change it or
 * the target stops at another breakpoint.
