[Help] AHK topic

I want to use AHK for sending a simple raw keystroke to QuakeLive. Cant get it work tho, for example:
if sending +moveup, (jump) nothing happens. If i do it with console down i can see its printed in console but the jump is not executed in game. When i close consol command is executed.
Any1 know how to send a keystroke, ex +jump, the correct way?

Sorry for bad english

Thanks
