Keyboard-shortcut for Firefox print preview?

Question

For testing the print output during web development, I find myself frequently pressing Alt+F followed by V. That is, open "File" menu, then execute "Print preview".

This is cumbersome.

Is there a single keyboard-shortcut for that?

In some browsers, this was possible via Ctrl+Shift+P, but nowadays this triggers private browsing instead.

Is there some lesser-known undocumented keyboard-shortcut for that? Or, does provide Firefox any means to configure this shortcut on my own?

Answer 1

I found a slightly shorter sequence: F10 followed by V. This works because "File" is the first menu.

However, this is still cumbersome and I'd love get to know about a real keyboard-shortcut.
