They probably are what I want. As far as I know, getc() in raw mode can'd 
differentiate between F3, Shift+F3, Alt+F3, or Ctrl+F3. I need to be able to 
do that.

The only way I've been able to find to do that is to intercept press and 
release scan codes, keep track of the state of every modifier key, and when a 
non-modifier key is released, modify the released character accordingly. If 
anyone knows of an easier way, please let me know.
