How do i make this tool work with keys and not mouse? [closed]

So i am not really a scripter and i have been struggling with this for past 2 weeks.

This tools work with filtering enabled but i need them to also work with the keys not just the mouse.

This is the code that needs to be changed.

local Player = game.Players.LocalPlayer

script.Parent.Selected:connect(function(m) 
m.Button1Down:connect(function() 
    Player.Character.Scripts.Chip.RKick:FireServer()
end) 
end)

And this code leads to this.

script:WaitForChild("RKick")

local debris = game:service("Debris")
local Go = false
local Kick = false

script.RKick.OnServerEvent:Connect(function(Player)
    if Go == true then return end
    Go = true
    if Player.Character == nil then return end
    if Player.Character:findFirstChild("Torso") == nil then return end
    if Player.Character:findFirstChild("Right Leg") == nil then return end
    Torso = Player.Character.Torso
    RL = Player.Character["Right Leg"]
    Hip = Torso["Right Hip"]
    Hip.Part1 = nil
    W = Instance.new("Weld")
    W.Parent = RL
    W.Part0 = Torso
    W.Part1 = RL
    W.C0 = CFrame.new(0.5,-1.5,0.5) *  CFrame.fromEulerAnglesXYZ(-math.pi/4,0,0)
    wait(0.5)
    Kick = true
    W.C0 = CFrame.new(0.5,-1.5,-0.5) *  CFrame.fromEulerAnglesXYZ(math.pi/6,0,0)
    RL.Touched:connect(function(hit)
    if Kick == false then return end
    if hit.Locked == true or hit.Anchored == true then return end
    F = Instance.new("BodyVelocity")
    F.Parent = hit
    F.velocity = RL.CFrame.lookVector * 50
    F.maxForce = Vector3.new(4e+006,4e+004,4e+006)
    debris:AddItem(F,0.5)
    end)
    wait(0.5)
    Kick = false
    W:Remove()
    Hip.Part1 = RL
    Go = false
end)

How could i make this work on key like Z,E or any other keys?

Please help.
