If I may suggest using and being proficient with Vim might help you not be as distracted with backtracking and in general increasing joy of writing.
Can you share why you think so? Vim is my go-to editor for most things, except when I am coding (sorry, hardcore Vim users!), and I find myself backtracking and editing sentences as I write, all the time. I am eager to learn what helps you not backtrack when using Vim.
