Is it possible to make enter or ctrl-enter close the pop window?

I have added the Python button to the quick access bar at the top of OneNote so that I can access it with the keyboard shortcut Alt - 6 and this has saved me a lot of time. However it would be amazing if I could just press enter to click on the pop box, do you think it possible to make the focus/selection start on the OK box?

If you don't need to make any changes in pop up box, you can use Quick Style option. In that case, pop up will not be shown and last used settings will be applied. If you had different use case in mind, please add more details.
