// Keybindings come from a preset: a file in the "keybinds" folder next to this file, or one of
// the presets built into Zellij ("default" and "unlock-first"). Print a built-in preset with
// "zellij setup --dump-keybinds <name>".
// "primary", "secondary" and "unlock" set the leader keys of presets that use them.
// If a leader key is empty or two of them are equal, Zellij warns and uses the default preset.
// Keybindings that come from a layout are shown in the settings screen but cannot be edited there.
// Bindings inside the block are applied on top of the preset. To replace the preset
// completely, add clear-defaults=true to the block.
// For a single session, "zellij options --keybinds-preset <name>" (and --keybinds-primary,
// --keybinds-secondary, --keybinds-unlock) choose a preset without changing this file.
