You posted in the wrong forum, anyway..

For auto response, try reading /help ON TEXT if you needed more information. In your remote (ALT R) add in:
Code:
on *:TEXT:*hello*:#:msg $chan Hello $nick

Beware, that will reply "Hello Nick" whenever someone had "hello" in anywhere of their sentence, eg: "Woogie boo boo hello dee dee" or even "marshello"

For the shortcut commands, you can either do it via ON INPUT, or as an ALIAS (shortcut usually refers to ALIAS)

Add this to ALIAS section in your script editor, ALT R -> click ALIASES tab.
Code:
h { msg $active hello }
hl { msg $active hello }
