Game Input MultipleXer

Guys I tried to make a macro for quick prone for call of duty.
I use "C" to crouch and I want to press LCTRL to go fully prone without holding the button. Heres what I writed tell me whats wrong;

CODmw.xml/CODmw.txt

MACRO JBUTTONDOWN c
KEYDOWN LCTRL
DELAY 1
KEYUP LCTRL

I suppose the long press should make the character prone?

Try

MACRO KEYDOWN c
KEYDOWN LCTRL
DELAY 1
KEYUP LCTRL

thank you I will try
