You need to set a keyboard hook.

Register a global hot key, monitor for global key presses (GetAsyncKeyState) or use a system wide low level keyboard hook.

Heres how i do it sometimes. I did it so the code executes once if you hold the key down.

Code:
#Region "Keys"

    Private Declare Function GetAsyncKeyState Lib "user32" (ByVal nVirtKey As Keys) As Short
    Dim hKeys As New Dictionary(Of Keys, Boolean)

    Public Function Keystate(ByVal key As Keys) As Boolean
        If GetAsyncKeyState(key) <> 0 Then
            If Not hKeys.ContainsKey(key) Then hKeys.Add(key, False)
            If Not hKeys(key) Then
                hKeys(key) = True
                Return True
            End If
        Else
            hKeys(key) = False
            Return False
        End If
        Return False
    End Function

#End Region


Create a timer with low intervals, something like 50 milliseconds.
Then just use it like this in the timer
Code:
        If Keystate(Keys.Insert) Then
            'Do something when Insert is pressed
        End If
        If Keystate(Keys.F1) Then
            'Do something when F1 is pressed
        End If
