Is it possible to trigger the expander differently?
I already have zsh-magic-dashboard running on empty enter.
Yes, when you configure the expander based on the readme change the ^M (enter key) on the following line to any key you wish:
bindkey "^M" empty-enter-expander
^E represents Ctrl + E M-e represents Alt + E ...
I use this wrapper to achieve that as of now: https://github.com/diagnoseme/docker/blob/master/bin/connect...
