1. A Glove - It meets the criteria of the riddle. No living creature, just an item made by human :-)
2. A keyboard - it has keys, one of them being space, other enter without their other meaning.
3. The shadow - They are formed when objects are obstructing the light. If other source came from other direction will light the "shadow" area and it will not be visible anymore (the shadow is not going anywhere, it is just a difference in brightness on a surface).

I tried to answer without reading the 1 comment till now.

I think at some point answers can't be so different :-) but it is fun.
So, maybe will find you again in posts.

Cheers
