ใช่ global hotkey ป่าวครับ ถ้าใช่ลองดูนี้ Code (VB.NET)
Private Declare Function GetKeyPress Lib "user32" Alias "GetAsyncKeyState" (ByVal key As Integer) As Integer
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If GetKeyPress(Keys.Enter) Then
MsgBox("TEST")
End If
End Sub
