alt key not pressed

Anybody got a clever way for the access key for a button to not work if the alt key is not pressed? If you call a button &Save and any control on the form that cannot accept text entry is in focus pressing the 's' key will raise the &Save button's click event even if the alt key is not pressed. I've wrapped a button and caugt the click event and mouse up event and checked if the alt key is pressed along with the access key. I then call a Clicked event to use on forms. Works OK but is not very elegant. Any ideas.
