In IRSSI, I've always been able to use alt3 or alt5 to jump directly to specific windows. That seems to have stopped working. I think it probably happened with the update to 15.04, but I can't swear to that.
I can still use alt-> or ctrln to cycle through windows but I don't see a way to hop right to the window I want anymore. So ... how do I get that functionality back? Or is there a new way I can hop straight to a specific window in irssi?
