Not a good approach because it isn't accurate even if  you perceive it to
be so. Control+c or control+s is implemented by the application you are
using. Just because all the apps you happen to use follow those
conventions, there is nothing any more global in the scope of control+s
verses alt+f to open the file menu in an application that has a file menu
with F as the excellerator key.

There are conventions that are associated with these keys, but is it even
helpful to spend time trying to formulate a difference in the studen'ts
mind with an explaination of the conventions? As the student learns the
common useages he can formulate any useful understanding of the conventions
he wishes. Really understanding the conventions means picking up on
concepts and lingo to understand the myriad of Windows objects (menus,
dialogs, buttons, lists, ........), which could be confusing overload to
the student who would ask this type of question.

And soon enough, the student will start learning useages of the keys that
violate the common conventions anyway.
