In Windows, you can switch the left and right buttons.

But,in Windows,set the right button to main button,after,in MC "Controls" interface,you set a control to right button,describe still is:"Left button".

Here, I have two suggestions(Choose one):

1.Left button is left button,right button is right button,change the detection of button attribute to the detection of mouse button;

2.Change the description of "Left Button" to "Main Button",and Change the description of "Right Button" to "Secondary Button".
