Focus out of document

I integrated spreadsheet in my codeigniter web app. When i was opening a spreadsheet, my pointer is inside functioning the movement of spreadsheet.

Is there a way, short cut key or any other function i can set a short cut key to focus out of the spreadsheet (iframe) and back to the parent web?

In fact, i simply want to press 2 time “esc” to move out of spreadsheet and backpage.

Hello @georgelee
I’m not sure that I understand the issue scenario right. Could you please record a videofile with demonstration of the issue and desired scenario?
