Any situation where characters communicate with gestures and motions, usually of the hands, as opposed to using voices. This is often done specifically to avoid speaking, either because somebody present is unable to hear or comprehend a given language, or because the characters are sneaking and cannot make noise. American Sign Language (and those Sign Languages that are not American) is perhaps the perfect example, allowing deaf individuals to communicate with one another through the use of sight rather than hearing.
Hand Signals are prevalent in reality as well as fiction. Whenever you indicate something by pointing at it, you're using a Hand Signal. Armed forces use them all the time, for convenience or stealth. Here, try it yourself: when someone approaches you, hold your hand out to them, palm-out, for "Stop." You didn't actually say "Stop," but the other person saw your gesture and probably knew its meaning intuitively. The "Cut-Off" signal, made by either pointing two fingers at your throat and waving back and forth or by drawing an extended index finger across your jugular vein, is also an example of a gesture with a universally recognized (not to say slightly disturbing) meaning.
This trope is frequently played for laughs, usually through Lampshade Hanging. Instances include a character misunderstanding a signal, thinking a character is gesturing meaninglessly when they are attempting to frantically make themselves understood, and the gratuitous use of hand signals when they aren't required.
This trope is not Body Language, and does not include habitual gestures like poses and tics. Also has nothing to do with Talking with Signs, which is about writing on wooden signs. A sufficiently developed set of Hand Signals may evolve into Talking Through Technique or an actual Signed Language.
