How can I use a script to move an object in Unity by a certain distance, for example by "1" with input.GetKeyDown?

Question

C++ / C#

there is a function:

if (input.GetKeyDown(KeyCode.A))
    {
      //плавно передвинуть объект (translate) на 1 по оси z влево
    }
else if (input.GetKeyDown(KeyCode.D))
    {
      //плавно передвинуть объект (translate) на 1 по оси z вправо
    }

When you press a key, you need to smoothly move the object using transform.translate (I believe) a certain distance.
Tell me how to implement it?

Tried inside the if function, but naturally when you press the key - the movement occurs 1 frame and stops.
I tried using bool and using other methods, but during the first movement, the animation is saved, and during subsequent movements, it does not move, but teleports the object, i.e. for 1 frame.
