Change controls - deconstruct

[Padre_Jaroslav]

Hello,
I played Factorio on one computer where the deconstruction of a structure was done by holding left mouse key. Then I moved my steam account and the game to another PC and now the deconstruction is done by right mouse click. It´s driving me nuts and I am unable to change that, although I looked through the controls settings numerous times. Any advice would be very much appreciated.

Swap the buttons for "Mine" and "Build" in the settings.
