I would like to introduce a very useful script. In fact, he is not working. I mean runs but does nothing.  Well, maybe almost nothing. He teaches. Just check each Function step by step.   ; REMARKS: ; 1. before you start any example try to unfold all code section - you can close and reopen this tutorial script ; 2. each function says about "number of STEPS to go" ; 3. you must copy this script to SciTE4AutoIt to go follow these all steps _Tutorial_Example_1_Folding()
