It’s a keyboard shortcut that calls this script

#!/usr/bin/env bash
sleep 0.5
xte "str ::: spoiler Anti Commercial AI thingy"
xte "key Return"
xte "str [CC BY-NC-SA 4.0](https://creativecommons.org/licenses/by-nc-sa/4.0/)"
xte "key Return"
# TODO figure out how to print it self
#xte "str \`\`\`"
#eval $(sed -e "s/.*/xte 'str &'/" -e 'a xte "key Return"' "$0" )
#xte "str \`\`\`"
xte "str :::"

I wish it were a functionality of the lemmy frontend.
