I obviously use Libre Office and have for quite a while. It has command lines that go back to pre Microsoft and a program I bought called Einstein Writer. The first word processor that had a spell checker with it. It seemed unlimited at the time, all I had to do was enter the correct spelling of up to 1000 of the most used words that I misspelled! MS bought them fairly early on and poof! Word was born.

In all actuality, I use chrome and drive for most of my stuff today. It translates well and is fast and easy. I do use the Libre Office spread sheets because it's command lines go back to Lotus 1,2,3. It's the thing about old dogs and new tricks.
