I find it’s exactly identical to MSWord, but from the mso97 days before the Ribbon bollocks. I used o97 Word because it was like win3.1 Word … word-perfect? It’s been a while.

But, TL/DR, LOWord is like Classic MSOffice from when it didn’t suck. This will not help you adjust, but hopefully the knowledge that you’re going back to a better era of UX could help blunt the pain.

Go carefully, and have your favourite vice handy to goose the positive reinforcement loop.
