Emote - Voice inflection is not easily translated by typing; however, UO allows you to emote your feelings. By typing a colon ":" followed by a space, your text entry will be emoted. Your "emote" will be surrounded by asterisks and will be a different color than your normal speech. Emotes (emotions) allow you to suggest an action that your character is doing to immerse yourself in the environment. *kicks dirt* *twirls hair* *sighs* Many players also set up macros for common emotes, such as smiles, laughs, grins, frowns, etc.
Whisper - Use a semi-colon ";" followed by a space (e.g., ; Psst, wanna buy a chicken?). Whispered text can only be "heard" by characters immediately adjacent to you.
I assume that you are talking about UO *emotes*. That is about all that is said in the UO database. (will continue the searching and post any further I find. I know that there is other commands just can't remember what all they were)
