Couple of functionality questions regarding loops and echo

I've not played around with my Z2 much so far, but I have a couple of questions: -

1. When you set cue points via the pads, how can you clear a cue point from the mixer so that you can set a new one on the same pad?

2. I love the post-fader effects. If I'm using delay/echo, how can I set the frequency of the echo? Presumably I can just tap a button on the mixer somewhere to do that, but which one?

Oh yeah, where can I get a full manual for it? I can only find the setup guide.

Also, just a heads up to NI, but on the page that's linked to on the registration card where you go to download Traktor, it says that if you already have Traktor installed you can go to a different page to download the Z2 drivers separately, except when you click the link to go to that page, the drivers aren't there. Drivers for several other pieces of hardware are there, but not the Z2.

 

I got the answers to these questions elsewhere, so in case anyone else was wondering about this stuff: -

1. Hold down Shift and press the pad you want to clear.

2. Hold down Shift and tap the Flux button.

 

The manual is in the documentation folder in the program folder. You can also click help in Traktor.
