Chat command doubts

[YAKO SOMEDAKY]

I'm having doubts on the meanings of the actions of the chat.
Acting is when I do an action for the character?
Example: "Character" runs behind the counter.
Emote: is a speech or action with feeling?
Example: "Character" (nervous) Damn! How did I let it get away!
Chat: when a character is speaking or when I want to do something with it?
Example: Can I search for evidence?
OOC: When I say something player who has not to do with the game?
Example: People you saw the movie yesterday?
Story: is when I describe a scene or scenery?
Example: The apartment was dark, a big mess, seems to have been a fight.

Emote: is character thoughts or actions that don't need the GM's approval?
