This plugin provides a function __expand_brace to replace {1..3} into {1,2,3} in a command line.
You can make key binds with this function as below.
# Expand and execute.
# These key binds are already defined in the keybindings branch
bind \n 'type -q __expand_range; and __expand_range; commandline -f execute'
bind \r 'type -q __expand_range; and __expand_range; commandline -f execute'
# Expand only
bind \cx __expand_range
