Is this editor right for me?

Because I had to update my Mac’s OS in order to have working browsers, I can no longer use KompoZer to maintain my website. That program, like Adobe PageMill I used before it (beginning twenty years ago), allowed me to compose and edit in English, just as one would do on a word processor, and it converted my work to HTML which I could view and edit if I wanted to.

1 Will Komodo do that?

2 If it will, where can I find instructions, preferably in plain English?
