um.. yeah.. I'm one of the age sliders here.. and probably the one that slides the most and across the biggest range. I slide very very quickly.. Gen says I can shift not only between comments, but between the begining and end of the sentence.. so it's not exactly like what you talked about, but if I shift that quickly.. I'd finish the thought I had.. and then comment from the changed perspective. um.. not sure how much you want to say..
so feel free to ask if you want clarification.. sorry if this isn't the kind of experience to answer your question
