Here's a cool tutorial I wrote up (not leeched or anything

)
Hotkey. Search the tutorials thread.
or folllow this:
[php]Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vkey As Long) As Integer[/php]
Then add another timer
And under Form1_Load
[php]Timer1.enabled = true
Timer1.interval = 1[/php]
Then under your timer2.tick
[php]Dim F11 As Boolean[/php]
And then this
[php]F11 = GetAsyncKeyState(Keys.F11)
If F11 = True Then
Timer1.Start
end if[/php]
So then you have this
[php]Public Class Form1
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vkey As Long) As Integer
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Timer1.enabled = true
Timer1.interval = 1
End Sub
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
Dim F11 As Boolean
F11 = GetAsyncKeyState(Keys.F11)
If F11 = True Then
Timer1.Start
end if
End Class[/php]
Do the same for F12 as stop, so instead replace Timer2.Start with Timer2.Stop
