post editor buttons

This is strange. I used to have edit buttons in my post write area that included a drop down menu with ‘paragraph’ ‘h3′ h2’ h1 etc, and also a button for indentation.

I notice that it is gone now. Is there a plugin for this? I have looked through lots of the plugins looking to see if that is where it is, but no luck.

I don’t know when they “went away”. Maybe when I installed latest WP? I just know that they were included on my post edit button bar where we write. I never installed them either. They were just there, and now they are not!

So, does anyone know a plugin for this? I’ve looked but had no luck.

thanks.
