Instant Reroll specific trade from villagers using sign on workstation

1. Place sign on workstation
2. Type few letters or full name of item/Enchantment book (without space, use _ for spaces)
3. Right click on workstation to reroll trade, villager and workstation will show green particles if success, angry if failed

What to type on sign ? 

Normal item name like 

bread -> bread

white_wool -> White wool

Why sign?

You cannot ask villagers because you dont know how to say in hmmmmmm, so you write in on sign
Also you want to remember which villager offer which trade once you setup trading hall right?

Why particles?

To find villager roaming around….

What about enchantment books? 

For enchantment books, full name or starting partial name followed by enchantment level.
If level not specified, by default gives max level enchantment book

eff -> Efficiency 5

eff 3 -> Efficiency 3

I am still confused to figure out what to type I need whole list
