Automatically centering geometry orgin


I am very new to blender and while doing tutorials I realised that for some reason every time I scale, grab or extrude I need to shift-s , cursor to selected, hit peroid and then only continue working with the object or it goes completely wrong.HOW do i make this automatic ? Its driving me nuts and I have no idea what to search for…


Cursor controls are found to the right of the Interaction Mode and 3D View Shader controls (lower left corner of the view-port). Bounding Box or Median Point is probably where you want it for most editing operations. Hitting period sets the pivot-point to the cursor, and hitting comma sets it back to bounding box.
