| $chan.key Returns the key of a channel | 
| Usage | 
| <string> $chan.key <string> $chan.key(<window_id:string>) | 
| Description | 
| Returns the key of the channel identified by <window_id>. If no <window_id> is passed, the current channel key is returned (assuming that the current window is a channel at all). If the window is not a channel, a warning is printed and an empty string is returned. If the channel has no key set, an empty string is returned. Alternatively, you could use $chan.modeParam(k) to get the current key. |
