I'm gonna blow your mind now:

- You can have multiple layers

- You can choose "a" to act as your control key when held down, but create a "gaming" layer that disables this feature, so you'd have your "WASD" direction keys back for the game and hold them down to move around.

- You can have a mouse layer, which mean if you hold down a key, some other keys will control your cursor. I normally use this to scroll up/down (mouse scroll buttons) wherever page up/down keys don't work.

- You can add snippets and macros to some keys to automate something you type a lot (your email for example).

- You can configure the keyboard in a way that your finger don't need to travel more than one key away from the home row.
