On a null layer, apply the "Slider Control" effect. In the camera or the =
text, (not both) change the position expression to be:
(whatever is already there) + [0,0,---SLIDER---] For "---SLIDER---", use =
the pick-whip to select the number field of the slider effect. Then any =
changes to the slider will be added to the Z-parameter of your position. =
to change position over time, simply keyframe the slider values.

So if you made the change to the text position, the expression might =
look like:
thisComp.layer("Camera 1").transform.position + =
[0,0,250+thisComp.layer("Position Control").effect("Slider =
Control")("Slider")]
or:
thisComp.layer("Camera 1").transform.position +  [0,0,250] + =
[0,0,thisComp.layer("Position Control").effect("Slider =
Control")("Slider")]
