you will get those things down... it is really easy... for instance, if you want to bold a sentence, then just put a pound sign in front of the sentence with a space.
this will make it bold (you will see this)
but I put it like this (no parenthesis):
(#)(space)this will make it bold
And you are a quick learner... ohhh one more thing, the more # signs the smaller your font will go... so you can do 1 # or ## or ###### ... from 1 to 6 ;)
