on [<modes>]send_action [<serial#>] [-|^]<match> { <action> }

This hook is triggered whenever the client sends a CTCP ACTION to a channel or to another person.

To display separate messages for public and private actions:

 on ^send_action "*" {
    if ( ischannel($0) ) {
       echo * $0: $servernick() $1-
    } {
       echo *> $0: $servernick() $1-
    }
 }
