Is it the F15 for reset and F16 for pause you want to set up if so run the script first then open Trackir in your profile select the drop down menu for center click on the set key box and press the pinky leaver it should say F15 do the same for the pause key exept hold the pinky leaver for 1 sec and you should get F16 for the pause.
if you want to change the keys for trackir the script uses look for this line at the bottom of the script
MapKey(&Joystick, S4, TEMPO(1000));USB[0x6A], USB[0x6b],
S4 is the pinky leaver change it to what you want to use
USB[0x6A], USB[0x6b], is the codes for F15 and F16
if you click help at the top right of the script editor all the USB codes are in the manual near the bottom change them to the key u want.
If you want to use Trackir like it is setup here in your own GUI profile you can only do it using the scripteditor its easy to do tho , I use the GUI to do most of the stuff I need, then in the GUI editor click view script copy the script (Ctrl+C) close the GUI open the script editor and paste the code (Ctrl + V) and just add MapKey(&Joystick, S4, TEMPO(1000));USB[0x6A], USB[0x6b],
