# mojibake configuration.
#
# This file is both the runtime configuration and, via `include_str!` in
# src/config.rs, the compiled-in default set. User settings in
# $MOJIBAKE_CONFIG/config.toml override these per individual binding;
# anything not listed here keeps its default. (MJB-LLR-180, MJB-LLR-182)
#
# Key syntax: "<k>" for one key, "<g><g>" for a sequence, with the modifier
# prefixes ctrl-, alt-, shift-, e.g. "<ctrl-d>".
#
# Bindings follow the Helix default keymap: https://docs.helix-editor.com/keymap.html

# Editor settings live in their own table rather than at top level: the
# top-level struct uses `#[serde(flatten)]` for the data/config directories,
# and config-rs stringifies values it buffers through a flattened map, which
# breaks integer and boolean fields. (MJB-LLR-185)

# Consulted by App before any component sees the key. A match here is consumed
