How to hide jump bar

So I typed J to show the jump bar to start learning it. But if I don’t type any command, how can you the hide it? I can’t find any way except to close the project. I know this is a sort of obscure corner case as one would normally invoke it to actually do something.

Pressing “Esc” key works for me…

Clicking on the page works here.

Thanks all. Both work for me, now. I think something was just clagged up temporarily. These things can happen.
