Discussion on: Passing a parameter to a zsh keyboard-shortcut

btw, the code in your example doesn't display any output for me. The branch gets created but I can't see the output from echo or git checkout. After some googling I suspect it might have to do with using a multiline prompt.

for some reason that I don't fully understand, adding a newline after git checkout makes it display for me:

function featbranch() {
    branch_name=$BUFFER
    zle backward-kill-line
    echo "git checkout -b feat/$branch_name"
    git checkout -b "feat/${branch_name}"
    echo "\n" #¯\_(ツ)_/¯
    zle reset-prompt
    zle redisplay
}
