Admittedly I struggle with emacs out of the box. My emacs configuration has evolved over the years. It's a personal thing. I couldn't tell you about my key bindings. My hands just know them instinctively. That's what I love about it. You can craft it to your personal needs. I map ctrl key to spacebar (only when spacebar is held down), and meta to return key (when held down). No more RSI for me.
