All the time? I search in my history, re-launch past commands, etc.

Now it's typically recent history, usually same day.

I know about the shortcuts etc. but I also need to at times pipe history into other commands so I've got a two letters alias:

    h?

Which greps into my history. I use that h? all the time.
