In PoE 1 It's so easy to take a look and read about the enemies when the entry is a button click away. In PoE 2 I forget it exist most of the time, and if I want to check something, like what kind of enemy is this, I have to go into the journal, go to the Cyclopedia Tab, click on the bestiary, and then guess what kind of enemy type the enemy I'm looking for might be. And I don't know if the enemy I'm looking up is under wilder or primordial, that's why I'm looking it up! 

So please tell me I'm an idiot and you can just hover over the enemies and press a key to go right to their entry. 

If not is this something that can be accomplished through a mod? I find it very curious that it's a feature that got lost from 1 to 2

There's no shortcut sadly.
