_Italic line_ (upper case “I” used)  
_Italic line_ (lower case “i” used)  
**Bold line** (upper case “B” used)  
**Bold line** (lower case “b” used)  
Underline line (upper case “U” used)  
Underline line (lower case “u” used)  
I’m doing this because I key in posts on my PC and then I copy-and-paste to the board; the computer has a tendency to captialize a free-standing “I”, for example.
