Reply to A few traktor mapping questions

I am using a VCI-100 FW1.3 with the 2.5 tsi mapping, but i wan't to change a few things:

1. How can i change the pause and play buttons to 1 play/pause button and one button to or set cue point or jump at latest cue point, just like it actually is in traktor. I don't like how it is mapped in the 2.5 tsi.

2. How can i change the FX that are used for EQ FX?

3. If i look at the mapping via traktor settings > controller manager. I can see some things are mapped double and are set as button in and button out or something like that. What does that mean?
