有没有精同多个子窗体情况下的快捷键有关问题的达人

有没有精同多个子窗体情况下的快捷键问题的达人？
本人在一个父窗体中打开了子窗体form1和子窗体form2，form1中有个按钮（【导出】并设置了快捷键s），form2中有个按钮（【删除】也设置了快捷键s），当前焦点在form2上使用alt+s为什么会响应form1上的【导出】按钮，而form2中的【删除】按钮确没有反应，求精通人士解答。

我用以下代码简单测试了一下，没有发现lz所说的那个问题啊。

VB.NET code

Public Class Form1    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click        Dim frmA As New FormA        frmA.Show()        Dim frmB As New FormB        frmB.Show()    End SubEnd ClassPublic Class FormA    Inherits System.Windows.Forms.Form    Public Sub New()        Dim btn As New Button        btn.Text = "Button(&S)"        AddHandler btn.Click, AddressOf ButtonClick        Me.Controls.Add(btn)        Me.Text = "FormA"    End Sub    Private Sub ButtonClick(ByVal sender As Object, ByVal e As System.EventArgs)        MsgBox("FormA")    End SubEnd ClassPublic Class FormB    Inherits System.Windows.Forms.Form    Public Sub New()        Dim btn As New Button        btn.Text = "Button(&S)"        AddHandler btn.Click, AddressOf ButtonClick        Me.Controls.Add(btn)        Me.Text = "FormB"    End Sub    Private Sub ButtonClick(ByVal sender As Object, ByVal e As System.EventArgs)        MsgBox("FormB")    End SubEnd Class

注意这两处：
1、Public Class FormA
   Inherits System.Windows.Forms.UserControl


2、Public Class FormB
   Inherits System.Windows.Forms.UserControl
