Main Iteration is the primary cycles that need to be run by this software. To run Main Iteration, you need to record mouse coordinates, Delay value, and Repeat value. Though Delay and Repeat is already have default value, you should set it up to your need.
Example case:
You need to run mouse clicking routine with 3 coordinates and need to be run for 20 times. Every click will need approximately 2 seconds delay. So for this, you need to record that 3 coordinates first, then set delay value to 2,000 (please keep in mind that this is in milliseconds), and then set repeat value to 19 (please keep in mind that to run 20 cycles, the repeat value need to be set at 19). Press start and wait for the software to finish.
