A family of Microsoft word processing software products for creating web, email, and print documents.
I think I found a fix.
Go to Settings>Accessibility>Keyboards>Full Keyboard Access>Commands
In here, you will see a list of commands and a keyboard shortcut key associated with it, there is one called “Activate” and the shortcut is the Spacebar. I changed this to Ctrl+Shift+R (a random combination) and saved it.
It seems to work fine now on Onenote, no issues with Safari and Messanger. I have not tried it on Word, PowerPoint or Excel. I hope this helps :)
