Mesh Attributes?

Hi,

I’m just getting started with Blender and have a question:

When I add a UV Sphere (or a Circle, Cylinder etc.) there’s a bunch of attributes shown at the bottom of the Tool Panel that can be changed (like Segments, Rings for the UV Sphere). But the moment I move or even deselct the object, these attributes disappear and in order to change them I have to delte the Object an add a new one. Now, ist there a shortcut to toggle this menu on and off?

Thx for the help.

Once you accept the change and the parameters disappear there is no way to get these back again

Oh. That’s bad. Means I have to concentrate alot ;). Anyways, thanks!
