Holding down button for repeat

Working on getting uirt set up with girder for my htpc, but the one thing I can't figure out is how to get it to repeat the key pressed when I hold down the button
Example holding down volume + to continue to raise volume without multiple key inputs.
I notice that when I hold down the button, the light on the uirt flashes, but nothing seems to be going on. I have to release and press again to get anything to happen.
Any help would be much appreciated.
Thanks
