i love my 60% keyboard. i rebound the caps lock key to be a modifier key that swaps the functions of several keys on the keyboard. i basically have two keyboards stacked on top of each other that i can switch between at will. e.g., when caps lock is held: the number keys turn into Fn keys, WASD turns into the arrow keys, and N, M, < turn into the volume down, mute, and volume up keys, respectively.
i also changed the rgb colors on the keyboard so this is all color coded in case i forget.
One of my many 60% boards has a split spacebar which I use as modifier / layer toggle. Been using 60% since the original KBC Poker; I should really design some printable cases now that I think of it.
