May someone please help me?

I am making a fighting game and I want to know how I would make it so when you hold down 2 keys it'll do another move
for example I have made it so by pressing S you can grab a knife but I want the player to be able to throw said knife by pressing both S and D(same time) , how would I do this?

Check if a key has been pressed just like you are now but instead check if two keys are down instead of one. You would probably want to allow something like 10-20 milliseconds to pass before treating the keys as "down" because it's unlikely that the player would press down two keys at precisely the same time.

Here's some psuedocode:

do message loop:
    if event is keyboard event:
        keys_down.push(event.key)
    if event is time event and time passed since previous update is 10 ms:
        if keys_down is ["S"]:
            player.grab("knife")
        if keys_down is ["S", "D"]:
            player.throw("knife")
