If you're talking about Emotes (bowing, sitting, sleeping, etc), those are ONLY usable with certain mods (like Jedi Academy or JediMod, etc), and they're for multiplayer.
To find out how to use those emote taunts, read the documentation for the various mods that support them.
Normally the only "gestures" Kyle can do are spinning his weapon in his hand (single player) or doing a "come here" taunt (Multiplayer). Those are accomplished by binding a key to taunt
Kyle going "invisible" is an exploit that was removed in the patches. Unless you're talking about Mind Trick, which is simply a force power and bound just like anything else.
