I'm trying to bevel an object, but I can't see any option for that. I've tried using the CtrlB shortcut and Mesh > Edges > Bevel. But as it can be seen in the screenshot, there is no option for that.
I'm using Blender 2.62 in Ubuntu 12.04 LTS. I'm not sure, but I think I downloaded Blender from the Ubuntu Software Center.
