How to transform a selection....

I choose a lasso in my selection tool


I draw arround my drawing


I press on [T] or launch the transformation tool


Handles appear and transformation parameters on the right panel


After that I can move, rotate, scale and flip my drawing

For example if I want to flip horizontaly I press on this icon



Or the other if I want something verticaly, and I click on APPLY or use [Enter]

Excellent!
