There are several hand gestures that characters might use to express hope, wishing good luck or trying to avoid bad luck. It can be accompanied by idioms like "fingers crossed", "keep your fingers crossed for me" or "break a leg". It might indicate that the characters are superstitious, but frequently it's just a natural part of BodyLanguage tropes. Mind that these hand gestures might vary cross-culturally.

* '''FINGERS CROSSED:'''\\
People cross their index finger and middle finger, sometimes on both hands. Generally it has the meaning of wishing for good luck or good fortune. Alternately, it may indicate intense hope or it can serve as anti-jinx measure. [[note]]The gesture has probably pagan or early Christian origins where the gesture was believed to ward off evil. Some scholars think that crossing your fingers is a way of making the Christian sign of the cross, and as such, it invokes a prayer or desire.[[/note]] This gesture is visually similar to LyingFingerCross, but as its meaning is positive, it's not hidden.
* '''THUMBS CLUTCHED IN PALMS:'''\\
Characters firmly clutch their thumb in the palm, and it can be done with both hands. It serves as wishing good luck for somebody else, or it expresses that a character ''asks'' the others to wish them exactly that.
* '''THUMBS UP:'''\\
Thumbs Up is a common gestures made by extending the thumb upward. It has several meanings (OK, number one, hitch-hiking, showing a direction, or an obscene gesture). It usually means approval or praise. Sometimes it's used as support or wishing good luck. Examples from fiction listed here should convey just the 'good luck' meaning.
* '''FIG SIGN:'''\\
Fig sign is a gesture made with the hand and fingers curled and the thumb put between the middle and index fingers, or the middle and ring fingers, forming the fist so that the thumb partly pokes out. In some areas of the world, the gesture is considered a good luck charm; in others it's considered obscene.
* '''KNOCKING ON WOOD:'''\\
A superstitious gesture used to ensure that a good thing will continue to occur after it's been acknowledged. However, it's sometimes used after speaking of an unfortunate event, which is likely to happen, so that it does not actually occur.
* '''JAPANESE "BREAK THE BOX" ANTI-JINX MEASURE:'''\\
The forefingers and thumbs of both hands are pressed together to make a box shape. Another person has to "break" the box shape with a downward motion of the forefinger.
