A very basic cheatsheet for the highline library.
(some short samples are probably more helpful than this short list)
##############################################################################
agree( yes_or_no_question, character = nil ) # return boolean
ask( question, answer_type = String ) {|question| ...} # string by default
choose( *items, &details ) # string
list( items, mode = :rows, option = nil ) # string
# Other modes available :columns_across , :columns_down and :inline
say( statement )
