@Diaa237 The Magic Remote is not natively set up to "emulate" the left or right Mouse buttons like on PC's/Laptops, as it is NOT like a mouse at all (other than they have BlueTooth commmunication). However, it is always possible that some APPS on the TV could software "emulate" that by requiring a particular coloured button to be pressed to be "equivalent" to a right-click, if it is ever needed for, say a compatibility reason inside a specific APP.
Where are you seeing this "right-click" asked for, on some odd site on the inbuilt browser maybe? I am very curious about your question.
