Need a shifted USB command

[sobe]

In the target script manual, there is no special key for KP+ so I will have to use a USB Code of 0x57. However, I also need this to be a shifted command which I understand in USB is 0xe1. What I able unable to do is to put the shifted command and the KP+ together in one command. For example, I have the following command line in target:

 

 

MapKeyIO(&Throttle, MSR, USB[0x57], AXIS(DX_THROTTLE_AXIS, -500, 20));

 

But I am unable to correctly add the left shift command 0xe1 together with 0x57. Any thoughts?
