The only difference is theat the first option allows the set for any single key, and the second option set for all keys?
Read here: https://www.autohotkey.com/docs/v1/lib/InputHook.htm#NotifyNonText
If true, notifications are enabled for all keypresses which do not produce text. Setting this property does not affect a key's options.
Can I unset it with InputHook.NotifyNonText := 0
What happened when you tried it?
