If you write your own blog, you’ve probably had at least one of those awful moments when you realize that you’ve done something you didn’t want to do.
Maybe you deleted an entire section and now you regret it. Maybe you inadvertently pushed something and ended up with an odd effect that you don’t like.
Not to worry! The curvy arrows on the toolbar of many blogging platforms are “undo” and “redo” buttons. They’ll take you back a step — they’ll put back that post you accidentally deleted, get rid of the ill-considered change in style, and just generally let you change your mind about actions you’ve taken.
The arrow going to the left allows you to undo things, or return to the way things were. If you decide against that, you can click on the rightward-facing arrow and get back the thing you just undid.
