Up, Down and Sideways

[Richmond]

Well, Linux seems to have no problem with  ctrlKey, so I am wondering 
about going for SHIFT and CTRL as
my modifier keys . . .

. . . However, I am well aware that on both Linux and Windows CTRL + 
some other key (e.g. CTRL + V) does something;
what I am not sure is that if I am running these things inside a keyUp 
statement, such as this one:

on rawkeyUp RUP
    switch
       case RUP= whatever the flipping rawkey number is for 'C'
         if ctrlKey() is down then
           do something jazzy
         else
           do something else jazzy
         end if
         break
     end switch
end rawkeyUp

the SWITCH condition will over-ride what the OS would normally do with 
CTRL + C (copy something).
