Repair cracks in tape & texture drywall?

[summutt]

We have an 11 yr old Skyline on concrete foundation. She's showing a couple of minor cracks in the T & T drywall. What's the easiest quick-fix? Is there a tape that can be applied over the crack? One crack runs on the surface of the ceiling in bedroom, about 8' long, to eaves, pretty much. Others are minor.
