A couple of people have mentioned middle-clicking enemies to target them in the past couple of days. (Thanks @QuackDuck and whoever else mentioned that. It's super useful.) Over time I realized you could right-click a block in build mode and focus the camera on the block you clicked, which made building in tight spots much, much easier. Control binding is also funky: I can't bind I, L, R or P to movement keys. As a left-handed person who likes IJKL for movement, that forced me to use numpad which has its own set of issues. P is bound to pause and I can't change it (or change the 'Pick up' and 'Turn camera' key) I, L and R do... what, exactly? Why can't they be used? What else don't I know about?
