Is there a way of pinpointing the line of an error when you have multiple tabs for a project?  For example, the console is telling me that my program is crashing on line 500, but I don't know where line 500 is because each tab starts with a line number of 1, and none of my tabs have more than 100 lines of code.  Do I need to add up the number of lines in each tab to figure out where line 500 is?
