This is the undo button. For example, you accidentally deleted all of your typing and said,
''NO! All of my hard work is gone. I don't want to type this **** again. Forget it. I'm not going to post.''
Don't worry. This button is here to undo the mistake you've made. It's like going back in time to change what happened in the past so you could see the effects in the future.

This is the redo button. There's not much to say about this button. I can't explain. All I can say is that it's the opposite of the undo button. Have fun.

This is the ''bold'' button. It bolds any word. For example,
MOYA. See how my name bolded? It's also used to highlight and point out mistakes in a person's post.

This is the ''Italic'' button. It's not from Italy. It slants words. For example,
MOYA. See how my name slanted? It activates when a person is quoted.
