A family of Microsoft word processing software products for creating web, email, and print documents.
I looked for a while and using hints here this worked for me:
My keyboard has the F1-F12 keys assigned icons (lock, airplane mode, etc). When I hit Ctrl, Fn,and F9 it does the Ctrl-F9 feature. When I hit the Alt, Fn and F9 it does the Alt-F9 feature. So sub the words Ctrl-Fn-F9 for Ctrl-F9 and Alt-Fn-F9 for Alt-F9 and it may work.
