Hello everyone,
I would like to know if there is a way to close a safari tab by pressing the middle button on any open tab.
I thought that I could get through it by assigning an action to the middle button when I use safari, but I could not define how to to check position of the mouse over a tab.
Tried the advanced trigger conditions but it was too deep for my knowledge.
that is the default behavior for middle clicks on Safari, you don't need to configure anything for this if your mouse generates a standard middle click
Oh man, that was dumb of me.
I had set a different function for the middle button in the LogiOptions settings and forgot that the default behavior is exactly what I wanted!! 
Okay, sorry about that, and thanks for the quick response!
