How in IRSSI can I switch channels? CTRL + number doesn't work I just installed irssi using Brew in High Sierra. Using iTerm 2, I can't figure out how to change windows (channels). Pressing CTRL 2 for example doesn't take me to channel 2 like it would on an Linux machine. 

Does anybody know the key combination that would make it work on iTerm and High Sierra?
My Google skills were horrible so I posted the question. Found out it is ESC+number.
