How do I disable launching applications via Super + Number?

[ShedoSurashu]

I think the terms in my question are too broad so when I do some Googling, I get non-related answers. So can anyone help me out and tell me how I can disable the behavior in Ubuntu 13.04 where press Super and a number will open up the corresponding app pinned to the sidebar? I want to use Super + number to change Workspaces instead and I don't need the shortcut to launching apps.

Also as an added question:
How do set the zooming (CompizSettings > Accessibility > Enhanced Zoom Desktop) to Super + Scroll Up / Scroll Down? I got used to OS X's mapping of this and would like to carry it over to Ubuntu.

I assume the settings are still in keyboard shortcuts as always in the past, but have no idea how you find that in unity other than using the dash.

I can't locate it on there hence, the reason I posted here.
