Post formats – trying an aside

Not sure I have full control over what happens when I try a different post format. This one is “Aside”.  Curious to see how it will appear. Just tried applying “Status” format to a post I made yesterday and lost the heading. Have previously tried “Quote” and did not understand what I was doing. There are a few more to play with too, but I think I may have to admit defeat and read the help info first or I might end up with some very weird-looking posts. Definitely need to learn how to use the “Gallery” format so I can do some better presentations of my old photos and cemetery pictures.
