live time

Ok so how do I tell the console to do fades with palletes during live shows. I have tried doing things like pos, time 3 enter or like live time 3 enter or time 3 For example, But It just doesnt seem to work right. What am I doing wrong. Also you know on the etc consoles where you can bring up a sub and record that and the cue will take it is there a way to do that on the hogs?
