-NixOS configuration
-===================
-
-My NixOS configuration! It configures most of the packages I require
-on my systems, sets up Emacs the way I need and does a bunch of other
-interesting things.
-
-In contrast with earlier versions of this configuration, the Nix
-channel versions are now pinned in Nix (see the beginning of
-[packages.nix][]).
-
-Machine-local configuration is kept in files with the naming scheme
-`$hostname-configuration.nix` and **must** be symlinked to
-`local-configuration.nix` before the first configuration run.
-
-I'm publishing this repository (and my [emacs configuration][]) as a
-convenience for myself, but also as a resource that people looking for
-example Nix or Emacs configurations can browse through.
-
-Feel free to ping me with any questions you might have.

-# Key bindings
-#
-# Each binding is defined as an object with some properties. Most of the
-# properties are optional. All of the alphabetical keys should have a letter for
-# the `key` value such as `V`. Function keys are probably what you would expect
-# as well (F1, F2, ..). The number keys above the main keyboard are encoded as
-# `Key1`, `Key2`, etc. Keys on the number pad are encoded `Number1`, `Number2`,
-# etc.  These all match the glutin::VirtualKeyCode variants.
-#
-# Possible values for `mods`
-# `Command`, `Super` refer to the super/command/windows key
-# `Control` for the control key
-# `Shift` for the Shift key
-# `Alt` and `Option` refer to alt/option
-#
-# mods may be combined with a `|`. For example, requiring control and shift
-# looks like:
-#
-# mods: Control|Shift
-#
-# The parser is currently quite sensitive to whitespace and capitalization -
-# capitalization must match exactly, and piped items must not have whitespace
-# around them.
-#
-# Either an `action`, `chars`, or `command` field must be present.
-#   `action` must be one of `Paste`, `PasteSelection`, `Copy`, or `Quit`.
-#   `chars` writes the specified string every time that binding is activated.
-#     These should generally be escape sequences, but they can be configured to
-#     send arbitrary strings of bytes.
-#   `command` must be a map containing a `program` string, and `args` array of
-#     strings. For example:
-#     - { ... , command: { program: "alacritty", args: ["-e", "vttest"] } }
-#
-# Want to add a binding (e.g. "PageUp") but are unsure what the X sequence
-# (e.g. "\x1b[5~") is? Open another terminal (like xterm) without tmux,
-# then run `showkey -a` to get the sequence associated to a key combination.
-key_bindings:
-  - { key: V,        mods: Control|Shift,    action: Paste               }
-  - { key: C,        mods: Control|Shift,    action: Copy                }
