Dear Mozilla Firefox Support Team, I am writing to inquire about the keyboard shortcut to display a PDF file in two-page view in Firefox. I have searched through the Firefox keyboard shortcuts documentation, but I have not been able to find this information. I frequently view PDF files in Firefox, and I would find it very convenient to be able to switch to two-page view with a keyboard shortcut. This would save me time and effort from having to click on the two-page view button in the PDF viewer toolbar. I would be grateful if you could provide me with the keyboard shortcut for two-page view in Firefox. If there is no such shortcut, I would also be interested to know if there is any way to create a custom keyboard shortcut for this task. Details of Browser I'm Using Mozilla Firefox 115.0 windows
