Information icons next to keys?

[blockninja124]

So I noticed recently that on some pages, theres a little info icon next to stuff that gives you a little explanation. However I was unable to find any of these on pages I could find the source of. Is there a way to do this in a custom page, and where could I have found the code that does this?

The information icon will check if a translation key exists that matches the field key + .help. So for instance loot_pool.rolls.help
