Thank you, never seen it before ! Very exaustive.

Ok, this is the method that apply transformation as the UI. I saw in
API and tested it in console without knowing conceptually what it
really does.

> I don't think it's great to intercept keystrokes. I think the reason why people might be frustrated (why scaling in Object mode doesn't behave as they expect) comes from a lack of understanding of how the tools work.

You're right, together with the possibility that a user could
customize his shortcuts in every moment.
First of all I learned how to apply the transformation in object mode,
this is very important.

But, talking in python, if a day there will be the need to know this,
how to call, from pycode, the mouse pointer with the pivot point for
configuring the desidered value ? ... As the scale UI function does.
How to call the scale function, from console, in a way that it's as we
called it from UI.
