Bit plain jane but it is handy to know and a hard feature to find. I used to have an edit button on my messages, wasn't sure if that was the same for everyone or just bite SMS but it's no longer there.
lifehacker is usually a lot more interesting though
To be honest both iOS and Android seem to be in competition to see who can make options and settings the most obscure. I mean why have a simple "edit" or "options" button when you can have some kind of obscure procedure that you have to google it to find out how you fucking do it (every time to use it because its so rare you use the feature you fucking forget)
