# Key bindings
#
# Some key-bindings are used exclusively in the normal mode, others exclusively
# in the insert mode, others in both modes.
# Some key-bindings are universal in the sense that they do not depend on the
# state of the player (view, mode, arguments), others are not universal.
#
# For fast processing, we propose the following.
# The mode (normal or insert) is stored in the FZF_INPUT_STATE variable. All
# key-bindings that are independent of the `view` and of the `arguments` are
# directly processed using a `--bind` with inline transform element. Keys that
# depend on `view` or `arguments` are processed through `$0 --fzf-key`. In a
# future step, we may also store the `view` part of the state as hidden fields
# in the list (the list generator makes that). Then, it may be possible to
# completely get rid of the state files. Even beter, we may store the view part
# in FZF_HEADER_LABEL.
#
# Switching between the modes (normal <-> insert) is done using two fzf `--bind`
# arguments. We make sure that only one is active.
