Pocket Guide

The Pocket Guide is a device meant to be helpful to new players. When in the Player's hand, it has infinite reach. If they left click on any Mob, Block, or empty space, the game will pause (regardless of whether Autopause is on or off) and a "wiki" page will open up. This wiki page does not contain as much information as those on, say, terraria.wikia.com, but some helpful information is still given, maybe some tips, too. If they click empty space, a page will open up about the layer the player is currently in.

Right clicking opens up a menu, similar to the Guide's "Crafting" menu, that has a single slot. Players can put items into the slot, and the Pocket Guide will list all crafting recipes for that item.
