A new line may be selected by right clicking anywhere in the Program or Sketch window and selecting Set Next Statement.


The Statusbar shows the Line number, Last Line number and the next code to be executed. If the AutoStep time is set to less than 2ms, the Status-Bar will not update until Run or AutoStep is stopped.
