You can find the Function locator box at the top left of the Code editor window. The Function locator contains all procedures (Sub) and functions (Function) present in your active script. The contents of the Function locator are automatically updated when you add a new procedure or function.
Select the name of a function or procedure in the drop down list to reposition the cursor to this function or procedure. If necessary, the Code editor will auto-scroll its contents so that the entire function is displayed.
