请教代码的意思，以及怎么才能触发该事件

[SP12345678902]

Option Explicit

Dim mItSkill As String

Private Sub cmdCalMonth_KeyDown(KeyCode As Integer, Shift As Integer)
Dim ShiftDown, AltDown, CtrlDown

   ShiftDown = (Shift And vbShiftMask) > 0
   AltDown = (Shift And vbAltMask) > 0
   CtrlDown = (Shift And vbCtrlMask) > 0
   If ShiftDown And CtrlDown And AltDown Then
        mItSkill = mItSkill & Chr(KeyCode)
        If UCase(Right(mItSkill, 5)) = "IAMIT" Then
            cmdCalMonth.Caption = "计算报表"
        Else
            cmdCalMonth.Caption = "计算月报表"
        End If

cmdCalMonth_KeyDown

"_"前面是控件名字, 后面是触发事件, 顾名思义就是当按键按下的时候触发事件运行事件代码.

[SP12345678902]

那什么时候能触发呢

[SP12345678902]

ctrl+alt+shift的时候吗

我按下任何一个键都会触发该事件

但是怎么实现ctrl+alt+shift同时按下呢？？？

该控件keydown的时候……
