Occasionally, I use Spotlight to quickly compute some expression because I'm too lazy to do it in my head, on paper, or fire up some program. Sometimes I would like to view the result again, but when hitting ⌘-Space again, it has disappeared. I'm not sure if this happens only when you search for something else in the meantime or also after some period of time.
The question is, can I somehow cycle back through my previous searches?
