How to unhide 'status-bar'?

Hi.

I was trying to figure out a way to hide/unhide the 'status bar' (not sure if
that's the term) showing the names of the windows. The one that shows up at the
bottom of the screen session by default.

So I did `prefix : hardstatus ignore` and the status bar went away.

But how can I get it back?

Any idea?

Thanks.
