FIXING ALT KEY in RHEL6

[victim_of_EMwaves]

Hey people,

Once Again I am here with my new bie questions

This time I am finding it hard to fix the issue of Alt+<Mouseclick> associated with windows.
I tried disabling Move windows option in the system>Preferences>Keyboard Shortcuts
I looked at other threads in the forum where most of the people had fixed this issue by changing move window to 'Super' by using this path

System>Preferences>Windows

I am using RHEL 6.0 and can anyone lemme know why I don't have that menu op]tion inside my system>preferences menu?

Attached is the screenshot of what configuration I have after making changes to Keyboard shortcuts:
