Thanks!!! This information was very helpful. It just so happened that I was able to use this editor's toolbar when making my initial submission here
https://steemit.com/introduction/@ainsleyjo1952/ainsleyjo1952-here-getting-her-toes-wet-written-on-july-13-14-2017

but couldn't find it when starting to write my second one.

Guess I'll just have to look a bit more carefully...
