// This is a completely modified layout that stikes a balance between muscle memory for keys, where I was coming from a standard
// Qwerty keyboard, and efficiency gained by using layers. I've switched tab and esc because it's more natural to me this way, and
// added layer switch on hold functionality for each key. Enter has moved to the key beside LOWER, to allow usage while still having
// the right hand on the mouse.

// Lower incorporates a numpad on the right side, and all of the symbols included on the left. There is logic for the symbols needed for
// calculators and math are located around the numpad, and coding symbols are placed in easy to remember spots.

// CAPS has moved to the Fn layer, and a few additional shortcut modifiers like CTRL_ALT_UP and DOWN for adding additional cursors in VSCode.
// Play/Pause has a prime spot on the base layer, and the Fn version skips to next track
