I look like I could be a gerund for a verb of ability, but I am not. Before the refrigerator, I helped keep your food from rot.

You say iT one way, I say iT anoTher. WhaT am I?

You can find me in homes under bridges and on the facade of a certain convenience food seller.

I have five letters, although you could say my name with only two. If your stomach were me, you'd probably want some food.

I have keys but open no locks. I have space but no room. You can enter, but you can’t go outside. What am I?
