Sorry if the header is a little confusing. What I am talking about is the bottoms along the top of the source editor, for doing things such as adding images and links. How do you add your own buttons of these? An example of a wiki that has this is the Pokémon Wiki, with two buttons: adding the word "Pokémon" and adding a redirect. If anyone knows how to do this, please let me know. Thanks!
I know it isn't actually relevant to your question, but it does have to do with your example. Interestingly enough, I have found that my Internet Explorer actually autocorrects "pokemon" for me. Not so for Chrome. I am not sure if that is due to something on my end or not but I was just reminded of that because of your example.
