from the body language link, I picked up a few things that I saw her doing.
Jutting
The chin can be used as a subtle pointing device and a small flick of the head may give a small signal that only people in the know are likely to notice.
Jutting out the chin towards a person exposes it and says 'Go on, I dare you, try to hit me and see what happens!' This can thus be a signal of defiance, if not towards the other person then instead towards some situation or person in the conversation.
Jutting may also exposes the teeth and is a thus a threat to bite which may be added to an aggressive display.
Pointing at a person with the finger is a threatening act. Doing it briefly with the chin is more covert and can thus be an insult.
Rubbing
When a person is feeling uncomfortable, the eyes may water a little. To cover this and try to restore an appropriate dryness, they person may rub their eye and maybe even feign tiredness or having something in the eye. This also gives the opportunity to turn the head away.
The rubbing may be with one finger, with a finger and thumb (for two eyes) or with both hands. The more the coverage, the more the person is trying to hide behind the hands.
Hand body language
The two hands can show different desires, for example with one forming a fist and the other holding it back, restraining the desire to punch the other person.
The hand can strike openly, with the palm or closed as a fist. The fist can strike forwards, sideways or downwards. One hand is often used for symbols as two hands as fists can be an invitation to fight (two hands held inwards can also indicate extreme tension).
Fist shapes and movements are often symbols of inner aggression. When moved towards a person, even a small amount, they signal aggression towards that person. A shaking fist signifies a strong desire to strike someone. Punching the air indicates triumphal excitement.
Hands can hide things. When people do not want to hear something, they put hands to ears. When they do not want to look, they cover their eyes. When they want to say something but feel restrained, they put their hands to their mouth. A hand may also cover a rudely open mouth, which may be opened in such as surprise or a yawn.
The hand may touch any part of the body in a whole range of situation.
Perhaps the most common reason for touching oneself is self-affirmation ('I am here. I am real. I am ok.') and related anxiety. Anxiety can be related to concern for the outer world or the inner world of thoughts and forecasts.
Touching is also used in romantic situations, where parts of the body may be lightly touched or stroked in simulation of desired or suggested action by the other person. The more erotic the parts being touched, the stronger the signal is sent.
Touching can also be a form of punishment, for example when a person slaps their head ('Bother - I forgot!').
Touching the other person can be an act of domination or of friendship, for example a hand on the shoulder whilst telling them off adds authority, whilst a gentle touch on the arm when sympathizing demonstrates concern for them.
Preening
Preening is a common action as the person brushes their hair and clothes, figuratively making themselves look more attractive and sending the signal 'Aren't I beautiful!' This is thus says 'Please like me' and may be a romantic invitation, a signal of superiority or indicate feelings of vulnerability.
Picking at bits of fluff clothes often shows disapproval as the person figuratively picks apart your argument.
Turning shoulders is a key part of turning away. If a person turns their shoulders whilst still looking at you, it probably means they want to leave (maybe because what you are saying is uncomfortable for them).
A person who is frightened or angry by the fight-or-flight reaction may well open their mouth to get more oxygen in preparation for combat or running away. This may also involve breathing faster (panting).
Oh my! I'll be over there awhile.
