Topic: Arc USB "Ext Inp"
I've searched Google, YouTube, and here, and I know this is probably incredibly basic, but I can't figure it out.
One of the buttons on the Arc USB (as well as the option to program other buttons this way) is labeled Ext Inp, or External Input. I've checked everywhere, clicked it, done whatever, and I just can't figure out what it does. So what does it do?
Again, I'm certain this is basic, I'm just at a total loss.
Thanks in advance.
