In these screenshots (which is the first page of my novel, The Influence), I use Open Office, but the concept should work the same for most word processors.
When formatting for ebook, using tabs is a no-no. But if you learned to type on a typewriter or before the days of needing to do your own formatting, tabbing became a reflex. I know; it took me forever to break the tab habit.
In any case, you can use the photos below to get an idea how to set your word processor so you don't have to tab. Once you get it set, all you'll have to do is hit enter after a paragraph and keep typing! Your indent will already be set.
And plugging for myself, if you need someone to format your work for ebook or print publishing, please consider my services. Thank you.
