Slide in/out

I have a R7S7G2 demo board with a touch screen. Later I will drive my own display. 

GUIX seems a good choice. But I want to make a menu that slides new items in, while old items slide out. Both horizontally (icons for for submenus) and vertically (for items text).

Ideally this would be triggered by the on-board CapSense slider and/or keys. 

Could someone point me to:
-  some demo using GX_ANIMATION_SLIDE_IN or GX_ANIMATION_SLIDE_OUT? 
- some info (tutorial) on how to configure and access the capsense keys? 

Thanks!
