have you tried events ? like this
Sub Save (
ByVal sender As System.Object, ByVal e As System.EventArgs) handles Savebutton.click,Control_s.click
'put save code here
end sub

Edit: o wait...... i didn't read your post properly 
I missed the acelerator part. a thought control s as a control named s (duh)
When you change the text like this "&Save" then you got a acelerator of <Alt S>
