Base Layer - Colemak

The base layout is Colemak by default, but this can be changed to QWERTY via the LOWER layer.

• I've implemented COLEMAK = SAFE_RANGE when enumerating the custom_keycodes, but I don't actually know what this does...

• Space cadet is implemented in the shift keys (hold for shift, tap for respective parentheses)

Layer Shifting

• The spacebar is a TAP_KEY macro - Hold for momentary LOWER layer, Tap for Space.
• The Right hand ALT key is a TAP_TOGGLE macro for the MOUSE layer (RAlt is accessible through LOWER, if you want...)

The LOWER layer contains a navigation cluster on the left hand. This layer is momentary when the spacebar or LOWER (RAlt) key is held and toggled on/off when the LOWER key is tapped.

• The Navigation cluster is offset to the right compared to the traditional WASD nav cluster. With this implementation, you don't need to move your hand from the home position when navigating. Page Up & Down keys are found on the far left of the cluster.

• All unused (blank on the above keymap) keys are locked out using the XXXXXXX filler (KC_NO), all modifiers (edge |_| keys [except 0, . & Fn] on the above keymap) and the ZXCV cluster are transparent (_______) to the Base layer.

• The base layer can be switched to QWERTY or COLEMAK by pressing the Pause Break or Scroll Lock keys respectively

The MOUSE layer contains keys replicating functions found on the mouse.

• The navigation cluster (Up, Down, Left, Right) is a replication of the Navigation cluster on the LOWER layer. The scroll keys are analagous to the Page Up & Downkeys.
• The primary click (right & left) buttons are on the right home row (index & middle fingers)
• Secondary click buttons are above the standard keys (M3/Wheel click, M4, M5) but I do not use this function.
