Alt+Any Key in KeyPress event

[yuleball]

hi, i am using rtb. I want to print a specific character when user presses Alt+some key by using chrW() method. I want to detect in KeyPress() event of rtb when user presses Alt+Key. How can i do that? I know i can detect (Alt+x) like combinations in Key_Down event of rtb and then i have used KeyCode = (decimal value of character to be printed). but its not working
