Automatic hide transform gizmo during selection in edit mode

As a newcomer blender user relearning modelling, there is one thing that is getting in the way which is the transform tool when I'm selecting either vertices, edges or faces. I suggest the approach XSI has to the problem which is quite simple in fact:

• When I need to select multiple elements, like edges for example I usually need to press a shortcut like ALT or Shift during this selection, basically whenever the user presses one of these keys the transform gizmo should vanish temporarily during selection and while one of these keys is pressed, once the selection is done and either one of the keys is not pressed anymore then the transform gizmo could reappear.
