Last command in same terminal - zsh

Question

When, in Bash, I have two terminals open, each maintain its own history, so hitting arrow-up always presents the previous command entered in that terminal.
In zsh the history is shared, so arrow-up presents the last command entered in either terminal. I rather like that ctrl-R gives me the full, shared history, but is there a way to make arrow-up give me the last command from the active terminal?

Answer 1

What says setopt ?
Maybe you have the option SHARE_HISTORY set.
You can unset it with setopt no_share_history or unsetopt share_history.
For more options look in man zshoptions.

Answer 2

I can't help you directly, but in my terminals, the command history is one for one terminal, so it's behavior you will expect. Below I print out my .zshrc file. Please play with it. I run my terminals with Yakuake.
