window add <target,[target]>

This adds one or more targets to the window's target list, without making it the window's query. If another window already owns the target, it will steal it.

Remember that target lists have priority to window levels, so messages to or from the target will go to this window instead of the MSGS or NOTICES window.

Targets are per-server. If you're connected to multiple servers, this won't affect the target on any other server.

Use window remove to remove a target from a window.

To have all messages you send to or receive from joebob go to this window:

/window add joebob
