Hot Keys

hey im tring to add hot keys in my VB6.0 hax, so i would type in

If GetKeyPress(vbKeyControl) Then
Command1_Click
End If

if i wanted to get control right?
so wat would i put in for the number buttons or the mouse keys. e.g. midle mouse button.

for the getkeypress line put it in a timer that is enabled and set its interval to 100. And i dont know about middle mouse button. I know that left mouse button is:

and right mouse button is:

so im guessing that middle button is:?
