Fundamental question on using Sikuli

1) As I see, Sikuli is based on "image recognition approach". In that case, it is compeltely "independent" of the technology with which my application has been developed in. This is because, I intend using Sikuli for creating automated tests in several of my Engineering applications that I use.

One of my application is a very old Engineering analysis application written in Fortran wheras another application is quite recent developed in C++ , .NET framework.

So, since Sikuli cocnept based on image comaprison and then peoforming keyboard/mouse action on objects, it does not matter at all if my application is developed in Fortran or .NET framework. AM I RIGHT?

I have not yet started using Sikuli but understanding the basics before I dive in and start swimming.

2) As I understand Sikuli is based on image recognition approach.

I have not yet started using Sikuli but understanding the basics before I dive in and start swimming.

Canyone just explain to me the approach (steps) Sikuli code will follow to do the follwoing

a)Go to start button on my computer
b) Open Miocrosoft word
c) Go to file ->Open
d) Go to C:\my_files and open a word file abc.docx

I just want to undestand the approach clearly on what images will eb compared in the above steps and how the image comparison will be used to peform keyboard/mouse actions.

I shall be grateful if someone just explains the approach relative to the above simple steps. Please can someon help?
