Ahhh, the stick map and not the keyboard map. Let me check.
EDIT- OK, using joystick buttons you can't or don't need the modifiers, Ctrl, Alt, Shft, when using the stickmap. The button you use would do the command.
If you want to use modifiers on joystick buttons you would have to use a macro for the joystick button and use the keymap to set the key or the joystick software to set the button up.
I use Speedkeys and only have my joystick buttons 1,2 and 3 set in keymap to enable CM eye so I have little actual experience stickmapping. I could be wrong.
