Sorry if I’m not using the right term…
1) I write the post in the WP interface.
2) I click to publish it.
3) I leave the WP interface and View Site to proof it, to see what it looks like when it’s published.
Sometimes I find a typo. What I used to be able to do is make changes to my text directly into my blog post without having to return to the WP interface.
(I can’t think of any other way of explaining it!)
