How do I declare the keycodes as strings instead of selecting the keys from a list? Such that the user can input a key in inspector window and it will be read?

public string StringKey = "a";

void Update () {

   if (Input.GetKeyDown (KeyCode.StringKey)) {

   }

As Phillipp mentioned, Enum.Parse, I used the following and it worked:

if (Input.GetKeyDown((KeyCode) System.Enum.Parse(typeof(KeyCode), StringKey))) {
...
