Freeze A Value

I am working in void Update, but there is a value that I only want to update when there is no arrow key input being pressed. If an arrow key is being pressed, I want the value to freeze until it is released, as if the string was updating only when no input is detected rather than every frame.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class PlayerController : MonoBehaviour 
 {
     public float speed;
     private Rigidbody2D rb;
 
     void Start ()
     {
         rb = GetComponent<Rigidbody2D> ();
     }
 
     public float thrust;
 
     void Update () 
     { 
         float horizontal = Input.GetAxis ("Horizontal");
         float horizontal2 = Input.GetAxis ("Horizontal2");
         float vertical = Input.GetAxis ("Vertical");
             if (transform.rotation.eulerAngles.z >= 90 && transform.rotation.eulerAngles.z <= 270) { //facing left
                 horizontal = horizontal * -1; //invert horizontal arrow keys
                 horizontal2 = horizontal2 * -1; //invert mouse buttons
             }
             if (transform.rotation.eulerAngles.z >= 180 && transform.rotation.eulerAngles.z <= 360) { //facing down
                 vertical = vertical * -1; //invert vertical arrow keys
             }
         thrust = horizontal + horizontal2 + vertical; //combine arrow key and mouse inputs
         thrust = Mathf.Clamp (thrust, -1, 1);
 
         rb.AddForce (transform.right * thrust * speed); //apply thrust
     }
 }

Here is the code in question. I want to freeze the values "horizontal" "horizontal2" and "vertical" (lines 23, 24 and 27) so that they do not invert their values while rb.AddForce (line 32) is being calculated
