Blender Help, Suddenly all your object move too much?

Example, when I try to move my camera by 1 pixel, it move 10 pixel, so what actually happened? after another 10 minute of search, i figure that it is because i accidentally click the "SNAP" button on bottom screen, the "MAGNET" icon, that will move every pixel by the setting you set such as 10cm every movement, just unclick it will get it back to 1 pixel per move
