receiving program must interpret. You are right to say that Windows does
tend to see things at a pretty low level. However, my statement is also
true; the "meaning" of the Shift, Alt, and Ctrl keys tends to be that they
modify other key strokes and don't (usually) get used as a key stroke by
themselves. One exception in Windows is that the pressing of just the Alt
key can activate the menu system for an application--though again, no
selection of a menu or menu item is made until some other "real" key is
pressed.
I didn't mean to get into the nitty-gritty details; rather I meant just to
point out the end result and something of the logic behind it.
