# Let's say I have a command like this

define-command fruits %{
  menu apple %{echo apple} banana %{echo banana} peach %{echo peach}
}

# I want to call the fruits command and select the first entry in a kakoune script

# This is what I've tried:
execute-keys : fruits <ret> <ret>

# But I get:
#    No such item: 
# as an error message

# How to programmaticaly call the fruits command and select the first option ?
