# Turns your listener on or off - you would pass the command toggle.selListener(below)
# to something to turn the event on or off. For example, in a kit that I built, I turned
# it on whenever Modo started up, and when I dropped in presets, I made sure to turn
# if off, because it would interfere(how I built it would). It all depends what you're
# needing out of it.

Ignore the spacing, I don't know what the problem is right now. It won't copy correctly through my clipboard for some reason.
