##
# ssty-list-functions-and-bindings: show keyboard shortcuts.
#
# The bash shell has a command `stty` that sets the teletype,
# including teletype functions and keyboard shortcut bindings.
#
# This script prints the functions and their current bindings.
#
# This script also massages the output the way we prefer:
#
#   * Translate the control key text "^" to "⌃" Unicode U+2303.
#   * Delete extraneous text, such as quotes, field separators, etc.
#   * One function per line.
#
# Example:
#
#     stty-list-functions-and-bindings
#
# Example output:
#
#     discard ⌃O
#     dsusp ⌃Y
#     eof ⌃D
#     …
