# Bind the function by using this in ~/.config/fish/functions/fish_user_key_bindings.fish
# function fish_user_key_bindings
#   # For example alt+q
#   bind \eq push-line
# end

function push-line
  commandline -f kill-whole-line
  function restore_line -e fish_postexec
    commandline -f yank
    functions -e restore_line
