[Minor] Unable to dismiss the keyboard shortcuts page

[inducer]

If I hit F1 to pull up the table of keyboard shortcuts, there doesn't seem to be a way to dismiss the resulting popup. Esc, F1 again, 'click outside' are the things I tried. Ultimately, a page reload worked, but... that seemed clunky.
