The various elements are modes of behavior. Some of them involve action, most involve your inner state and communicating this state.
You can see them all in the [Communication matrix]
I do not want to make a list or define them all here, but I will make two remarks.
You can see that the one mode I have not yet mentioned is “attention”. This means how you signal your awareness of and attention to your target.
During the first two phases, this is done primarily with eye contact (since you are not yet speaking to your target).
After that, it is most important that you signal your attentiveness by active listening. People like to talk mostly about themselves. If you signal that you are really listening, he/she will value your presence. There are techniques for this.
The blue-marked elements are applicable when your goal is a romantic/sexual connection, whether your object is another meeting, a date or something more physical.
