The insert key on my K780 is not working or if there is a way to make it work, I am at a loss. I have googled it, watched YouTube video, of course checked this software that is supposed to be to setup your keyboard and the instructions for the insert key does not work but then again your instructions are only up to Windows 10 and I am on 11. Maybe that makes a difference, but I have tried every combination of keys and nothing works. I need to be able to insert lines. Please advise. diane.lavery@gmail.com. Really disappointed.
