Using CompizConfiguration Settings Manager (CCSM), I've assigned hold super key + roll mouse button to zoom in/out. When I hold super key it by default shows shortcut list on Ubuntu 12.04. I want these two process i.e. zoom in and appearance of shortcut list not to occur simultaneously.

I did not find any useful tip on google.

My advice is not to fiddle with keyboard shortcuts. It's possible that, sooner or later, some thing will conflict. – user25656 Jul 25 '12 at 7:04
Yes, your'e right @vasa1 but I disable shortcut list on pressing super key for the time being. Zooming opting is more important to me for the time being. Secondly, I can roll back all the changes made in Compiz, if I encounter any shortcut-keys related trouble in future. – Chirag Jul 25 '12 at 8:28

You can either change the launcher key:

CCSM -> Unity Plugin -> Behaviour Tab -> "key to show launcher"

or disable shortcuts list:

CCSM -> Unity Plugin -> Experimental Tab -> "Enable Shortcuts Hints Overlay"

The second method is sufficient to achieve it. – Chirag Aug 10 '12 at 0:33
