Clarification:
Like Rob, I've had a lot of life issues, so it's been a while since I've used the interface. The buttons outlined by Parody in red and blue are the ones I'm referring to. If one set of those is new with 246, then something has changed.
What I recall, when I was doing a lot of input, and reverse-engineering the XML in the exports, is that one of set of those buttons would insert a bulleted list as plain text, with no XML or HTML to format the list. There would be XML and HTML surrounding the list, sure, but within the list itself, each item would include the bullet point as text, the text as text, then a CR/LF. Rinse and repeat.
Likewise with the enumerated list, one of the options would include the item number as plain text, the text as text, then a CR/LF. Rinse and repeat.
One set of buttons would format the list with the <ol> and <ul> tags, and one set would add the bullets and the numbers as plain text.
