如何通过按F4键使按钮工作并再次按F4键使按钮停止工作？

Question

我做了一个自动点击器。

现在有一个问题。当我运行代码时，它可以正常工作，但是会在我全屏（在游戏中）时单击。

当我想停止它时，我在菜单栏上按了应用程序，但它始终保持打开和关闭状态。

如何分配类似F4的按钮来运行代码？我不想按开始按钮，而是要按F4键。

我可以在编程上获得更高的分数（允许我使用该网站来获得更好的分数）。

这是我的代码：

Public Class Form1
    Declare Sub mouse_event Lib "user32.dll" Alias "mouse_event" (ByVal dwFlags As Int32, ByVal dx As Int32, ByVal dy As Int32, ByVal cButtons As Int32, ByVal dwExtraInfo As Int32)
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Timer1.Start() 
    End Sub

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        Timer1.Stop()
    End Sub

    Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
        Label1.Text = Label1.Text + 1
    End Sub

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    End Sub

    Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
        Windows.Forms.Cursor.Position = New System.Drawing.Point(Windows.Forms.Cursor.Position)
        mouse_event(&H2, 0, 0, 0, 1)
        mouse_event(&H4, 0, 0, 0, 1)
    End Sub

    Private Sub Button4_Click(sender As Object, e As EventArgs) Handles Button4.Click
        Label1.Text = 0
    End Sub

    Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
        Windows.Forms.Cursor.Position = New System.Drawing.Point(Windows.Forms.Cursor.Position)
        mouse_event(&H2, 0, 0, 0, 1)
        mouse_event(&H4, 0, 0, 0, 1)
    End Sub

    Private Sub Button4_Click(sender As Object, e As EventArgs) Handles Button4.Click
        Label1.Text = 0
    End Sub


End Class
