It issues the command specified (/set irc.server.[SERVER_NAME].nicks, but change "[SERVER_NAME]" to any specific server name you want), and repeats (using the shorthand character ") all of the arguments ("comma, ...") from the immediately previous command. This is faster than having to type them all over again.
