# TODO: If using --criteria on a window in another workspace, sway switches to that workspace
USAGE="\
${0} [--id|--criteria] <index|id|criteria>

Focus/hide the container at <index> in the scratchpad
Depends:
    jq

Args:
    --id: Use the given container ID instead of <index>
    --criteria: Use the given criteria instead of <index>
    index: The element index of the scratchpad (sorted by container id)
    id: The container id (if --use-id is specified)
    critera: The critera to use for swaymsg (if --use-critera is specified)

Caution: the list is sorted by container id - not the order it was put into the scratchpad...
         for more complex use cases, use either \`--use-id\` or \`--use-critera\`
