# Key bindings
# ------------
# For compatibility with fish versions down to 3.1.2, the script does not use:
# - The -f/--function switch of command: set
# - The process substitution syntax: $(cmd)
# - Ranges that omit start/end indexes: $var[$start..] $var[..$end] $var[..]
# The oldest supported fish version is 3.1b1. To maintain compatibility, the
# command substitution syntax $(cmd) should never be used, even behind a version
# check, otherwise the source command will fail on fish versions older than 3.4.0.
