# Basic Keycodes
The basic set of keycodes are based on the [HID Keyboard/Keypad Usage Page (0x07)](https://www.usb.org/sites/default/files/documents/hut1_12v2.pdf) with the exception of `KC_NO`, `KC_TRNS` and keycodes in the `0xA5-DF` range. See below for more details.

## Media Keys
These keycodes are not part of the Keyboard/Keypad usage page. The `SYSTEM_` keycodes are found in the Generic Desktop page, and the rest are located in the Consumer page.
?> Some of these keycodes may behave differently depending on the OS. For example, on macOS, the keycodes `KC_MEDIA_FAST_FORWARD`, `KC_MEDIA_REWIND`, `KC_MEDIA_NEXT_TRACK` and `KC_MEDIA_PREV_TRACK` skip within the current track when held, but skip the entire track when tapped.
