Can you have both? Local history and global history.

You have a command to switch which one is at play. 'gh' for
global history, 'lh' for local and 'th' for toggle.

That way you would also see what you would use. It is possible
you would actually just use the global one as you say.

How do I get global history for zsh?

I have this file in play - it sounds like global history, but
maybe it is session local, then? So it should be "live"
between sessions as well? How do you get that?

#! bin/zsh
#
# this file:
#   https://dataswamp.org/~incal/conf/.zsh/history

setopt appendhistory
setopt histignorealldups

HISTSIZE=1000
SAVEHIST=$(( 10 * $HISTSIZE ))

HISTFILE=~/.zsh-history
