Note that the `default_layer_state` variable only determines the lowest value to which `layer_state` may be set, and that `default_layer_state` is used by the core firmware when determining the starting value of `layer_state` before applying changes. In other words, the default layer will *always* be set to *on* in `layer_state`.
-The default layer is defined in the firmware by the `default_layer_state` variable, which is identical in format to the `layer_state` variable exlpained above. The value may be changed using the following functions:
+The default layer is defined in the firmware by the `default_layer_state` variable, which is identical in format to the `layer_state` variable explained above. The value may be changed using the following functions:
- `default_layer_state_set(state)` sets the state to the specified 32-bit integer value.
- AND/OR/XOR functions set the state based on a boolean logic comparison between the current state and the specified 32-bit integer value:
### 0.2 Layer Precedence and Transparency
-Note that ***higher layers have priority in the layer stack***. The firmware starts at the topmost active layer, and works down to the bottom to find the an active keycode. Once the search encounters any keycode other than **`KC_TRNS`** (transparent) on an active layer, the search is halted and the remaining lower layers aren't examined, even if they are active.
