How to close filepicker.io widget?

Question

When using filepicker.io, is there a function in the API to properly close the widget, or do we need to click on the x link or in the background?

We want to determine when the user presses the ESC or TAB key and closes the widget when this happens.

Answer 1

There is no api call to close the modal. Feel free to fire the click event on x.
