Control key hides Feedly mini search-results box -- can it be unhidden?

I've noticed that when I'm on a search-results page where the Feedly Mini search results box is activated, the box will vanish when I hit the control key. I assume this is intentional (though I don't know). I'd like to suggest that you make this option user-configurable (i.e., make it possible for me to turn it off). I control-click a lot to open tabs in new windows. This means that often I inadvertently hide the results box.

Also, I don't know how to make it reappear -- is it possible to force it to open? Reloading the page doesn't seem to bring it back.
