+# 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.
