You know beginner's find it very difficult to understand the way people post here whereas every necessary tools use to make up those write up are there via the functional key bottons, so op just break it down to easy understanding of newbies even using an arrow mark to indicate each function of the key, because remember when i was a newbie i only learn through someone's post by quoting the post to review how the work goes, so with that process i began to understand fully the concept of the tools uses to make a post.
