I've been playing on my iPad since 1.0, but recently switched to desktop because my iPad was lagging really bad. I'm still getting used to the controls, but I don't know how to switch from the Quests tab to the Crafting materials preview tab. Is there a button or combination of buttons I need to press? Please help, I tried all the buttons on the keyboard and I can't seem to find it online either.
