Is there a way to simplify this code?

So I am making a platform fighter game and for each move I have a ton of code that I think can be simplified but I don’t know how

//variables
public GameObject jab; //The jabbing hitboxes
private bool isJabbing = false;
private int jabTime;

//Check if button is pressed
if (Input.GetKeyDown(KeyCode.P) && isJabbing == false)
            {
                isJabbing = true;
                jabTime = 0;
            }

//Jabs for 10 frames then stops
if (isJabbing && jabTime <= 10)
            {
                jab.SetActive(true);
                jabTime++;
            }
            else
            {
                jab.SetActive(false);
                isJabbing = false;
            }

void Start(){
StartCoroutine(Jabs());
}

      IEnumerator Jabs(){
        yield return new WaitUntil(()=>Input.GetKeyDown(Keycode.P));
        jab.SetActive(true);
        yield return new WaitForSeconds(10f);
        jab.SetActive(false);
        StartCoroutine(Jabs());
}

@IrOn_KiT Well when you say shorten, I assume you also mean more readable. I’ve been experimenting using Pattern Matching with Switch Statements as an alternative to the classic If-Else statements and I went ahead and added some comments to my code and took the liberty of adding a few variables and features. This is probably how I would do it, but feel free to experiment and add your own twist.

public bool IsJabbing { get; protected set; }
public int Jabs { get; protected set; }

[SerializeField]
private GameObject jabHitbox;

[Tooltip("The amount of frames a jab lasts.")]
[SerializeField]
private int maxJabs = 10;

private void Update()
{
    // Checks that the jabHitbox has been assigned
    if (jabHitbox)
        switch (IsJabbing)
        {
            // The first frame when you are not jabbing and jab button is pressed
            case false when Input.GetKeyDown(KeyCode.P):
                IsJabbing = true;
                Jabs = 0;
                jabHitbox.SetActive(true);
                break;
            // When you are jabbing and hit the maximum amount of frames for jabbing
            case true when Jabs > maxJabs:
                jabHitbox.SetActive(false);
                IsJabbing = false;
                break;
            // When you are otherwise jabbing
            case true:
                Jabs++;
                break;
        }
}
