Blender 2.6: How to animate object rotation without adding a path?

I was wondering how i can animate an object in Blender 2.6 to rotate 360° in 10 Frames without adding a path.

How-i-fixed-it:

I found the right hints here:

1. Move to the framenumber, you want the animation to start. Select the object, set the start rotation angle in the object properties. Right click on the rotation value textbox and select "Insert Keyframe".

2. Move to the framenumber, you want the animation to end. Select the object, set the end rotation angle in the object properties. Right click on the Rotation value textbox and select "Insert Keyframe".

That's it.
