Close the insert video window with a keypress

Hi,

I’m learning how to touch type, and I want to stay on the “home row” as much as possible.

Currently, when I insert a YouTube video I press “Ctrl+L” and paste the URL, and then I have to use my mouse to click on “Insert” - could you please make it so that pressing “Enter” (or anything on the home row) confirms our selection and closes the window?

Thanks,
Stuart
