the "channel" ability?

What exactly is this supposed to do, if i give it to a hero and he learns it, it doesnt show up in the abilities field. I saw one of the blizz guys talking about it being a skill u can use that wont do anything, so you can link triggers to it, but i cant get my guys to use it...help would be appreciated ><

If u want it to be usable you have to do alot of things some thinng i cant even do, like this

uh...what?

What do you need it for? If you just want a hero to have a blank channeling spell, just make a starfall with no range.

ahh i figured it out, click the data - show ui field. And the reason i wanted to know is cuz i remember a blizz guy on the forums saying it was put in to be a blank channeling ability...and thats what it is, pretty nice ^^
