 Some keyboard implementations provide convenience methods for setting the state of the physical LEDs.

-The Ergodox EZ implementation provides `ergodox_right_led_``1`/`2`/`3_on`/`off()`
-to turn individual LEDs on and off, as well as
-`ergodox_right_led_on`/`off(uint8_t led)`

-In addition, it is possible to specify the brightness level with `ergodox_led_all_set(uint8_t n)`,
-for individual LEDs with `ergodox_right_led_1`/`2`/`3_set(uint8_t n)`

+In addition, it is possible to specify the brightness level of all LEDs with `ergodox_led_all_set(uint8_t n)`; of individual LEDs with `ergodox_right_led_1`/`2`/`3_set(uint8_t n)`; or by index with `ergodox_right_led_set(uint8_t led, uint8_t n)`.
 
-It defines `LED_BRIGHTNESS_LO` for the lowest brightness and `LED_BRIGHTNESS_HI` for the highest brightness, which is also the default.
+Ergodox boards also define `LED_BRIGHTNESS_LO` for the lowest brightness and `LED_BRIGHTNESS_HI` for the highest brightness (which is the default).
