Hotkeys and commands

Hotkeys are keys or key-combinations for use within a match which, when typed, provide quick access to certain aspects of the game. Commands can be typed into the chat console either within a match, or in other PVP.net chat windows, though some (such as champion laughter, jokes, and dances) will only have the specified effect within a match.

PvP.net provides players with the ability to chat with friends who are currently in an active session of League of Legends. For players in the AIR client, this process is as simple as opening a chat window through your buddy list. Players in-game will be able to send messages to players in the PvP.net client, or even in other games of League of Legends by making use of the following chat commands, followed by a message:
 * /w "summoner name" - will send a message to another player. Summoner names are case sensitive.
 * /r - will send a message to the last player who sent you a message. Note that it will automatically add the recipient after /r.
 * /all - will send a message to all players in the current match (useful if you forgot to press shift + enter).

PvP.net provides players with the ability to block unwanted messages from other players through the use of the following commands:
 * /mute "summoner name" - will mute all text from a player for the duration of your current game session.
 * /ignore "summoner name" - will mute a player during this game session and all subsequent game sessions.
