# It might be possible to attempt to share KBDs between `lf` and `dired`.
# Currently shared KBDs with `dired`:
# - D: delete file
# - R: rename file
# - +: create directory
# - c: create file
#
# The following command prefixes are used by lf (taken from the docs):
#
# : read (default) builtin/custom command
# $ shell shell command
# % shell-pipe shell command running with the ui
# ! shell-wait shell command waiting for key press
# & shell-async shell command running asynchronously
# / search search file in current directory
# ? search-back search file in the reverse order
#
# `x` will be used as a generic prefix KBD for most of my user-defined KBDs. Do
# not map anything to just `x`. Instead prefer `x<char>`. Mneumonically, "x" is
# intended to resemble "eXecute".
#
# If `x<char>` does one thing; `x<uppercase-char>` should do the opposite when
# possible. This is convenient for things that pass the round-trip test like
# encrypt/decrypt, archive/unarchive.
# TODO: move most of these commands to function.zsh and call those functions
# herein. Especially the `archive` and `extract` functions.
#
# TODO: consider integrations with `xdg-open` and configuring filetypes to
# behave in expected "dwim" ways.
#
# TODO: learn more about the terms "archive", "compress", "decompress",
# "expand", "extract", etc. See if a larger abstraction can be created on top
# without sacrificing too much nuance. This might be the case of "serialize",
# "deserialize", "pickle", "unpickle", "marshal", "unmarshal", "encode",
# "decode" -- in which case, a broader abstraction would be nice to decrease the
# surface area of the vocabulary.
#
# TODO: find a way to visualize all of the bound or unbound KBDs.
#
# TODO: support polymorphic way encrypt/decrypt a file or directory.
#
# TODO: support "toggle" for encryption/decryption that detects which function
# to run based on the extension.
