The current script being edited in the Script Editor is displayed in the Script Area. The Script Area features line numbering and syntax highlighting to make it easier to work with scripts.

Script lines that are marked with a blue dot to the left of the line are eligible for use as breakpoints. To set a line as a breakpoint, click the blue dot. You can also set a breakpoint by positioning the cursor in the line you wish to break at and clicking the Toggle Breakpoint option in the Script menu. To remove all breakpoints, choose the Clear All Breakpoints option of the Script menu.

To execute a selection of statements, highlight the statements you wish to execute and choose the Execute Selection option of the Script menu.
