/* This keymap is a regular 40s keymap for most. My concessions include no numpad, and a dedicated left-hand layer.
Enter is on a layer, which seems somewhat safe! 
Changes/improvements include removing all the Quantum mod functions when on the arrow layer, so that Ctrl and Shift act without ambiguity based on short or long presses.
The 3 LEDs on the board show Caps Lock/L1/L2 respectively. L3 has no LED.
