# bash is a little fucky at Alt-C or fzf-cd-widget so i found these 4 commands
# from : https://github.com/junegunn/fzf/wiki/Examples#cd
# Update: The cause of this bug was actually the conflict of Alt-C with config
# of st terminal for clipcopy key bind. So I changed that to Alt-b in the 'config.h'
# file or 'st_config.h' in this repository. now Alt-c works fine in the bash. so
# we don't need bellow functions but for completeness I don't remove them. Also 
# I add them to '.zshrc' file to have the same behavior in bash and zsh. Note that
# by solving this conflict the Alt-C works fine in zsh and we will use the same 
# default key bindings of fzf in zsh.
