in irssi, you can define as many completions as you like by simply input command:
/completion ty thank you
/completion -auto ltns long time for no see
so when you input ‘ty’ and press Tab, then ‘ty’ will be replaced by ‘thank you’. If you use -auto option, then when you input ‘ltns’, to get the completion, you can press Tab or just press space. Simple and powerful. Try it!
