When you click on the Balloon Icon left of the chat, you see lots of the actions your avatar can do. You can also type those out with the /

Sometimes one of the letters of that action is enough, like the /n for No.  Sometimes two, like /bl for Blowkisstofans and /bo for Bow.  When you type just /b , one time it will do the Blowkisstofans, another time the Bow.  Rule of thumb is, when you make it unique, it will perform that action.  Like /poi for Point and /pol for Polite bow.  Just try them all.

The same with the /c for the cage dances or catwalks for the ladies.  Type /cat for a catwalk and /cag or /cage for a cage dance.  Also, it is possible to type /catwalk0 and /catwalk1

The /d to dance or drink, will sometimes let you dance, sometimes drink.  When you always want a dance move, then type /da
