For ZSH, I've been using this in the ~/.zshrc file for years:

setopt HIST_IGNORE_ALL_DUPS
setopt HIST_VERIFY
setopt HIST_NO_STORE
setopt SHARE_HISTORY
setopt APPEND_HISTORY

This shares the history file amongst all Z shells, appends commands to  
the history, removes duplicates of that command from the history, and  
loads the history line retrieved by eg !54 into the command line for  
you to edit before you execute the command.

ZSH will always remember the 1 previous instruction executed from  
"this" shell. As you continue to scroll back through the history,  
you'll end up in the global history.

Enjoy :)
