Eclipse Keyboard Shortcut Does not Work on Ubuntu 12.04

When I installed Eclipse on Ubuntu 12.04 (or rather just unzipped the eclipse binary in my home folder and started the eclipse executable) some common Eclipse keyboard shortcut was not working, like Organize Import Ctrl+Shift+O or Inspect when debugging Ctrl+Shift+I. And the problem was that they were conflicting with the OS Ubuntu keyboard shortcut. To remove/edit the Ubuntu keyboard shortcut simply open Ubuntu Keyboard and walk through conflicting Eclipse keyboard short and either remove the Ubuntu keyboard shortcut or reassign them to other keyboard shortcut.

In the example below I simple removed the Ubuntu keyboard shortcut for Zoom in and Zoom out, since I don't need them.
