[docs]class Keycode:
"""USB HID Keycode constants.
This list is modeled after the names for USB keycodes defined in
http://www.usb.org/developers/hidpage/Hut1_12v2.pdf#page=58.
THis list does not include every single code, but does include all the keys on
a regular PC or Mac keyboard.
Remember that keycodes are the names for key *positions* on a US keyboard, and may
not correspond to the character that you mean to send if you want to emulate non-US keyboard.
For instance, on a French keyboard (AZERTY instead of QWERTY),
the keycode for 'q' is used to indicate an 'a'. Likewise, 'y' represents 'z' on
a German keyboard. This is historical: the idea was that the keycaps could be changed
without changing the keycodes sent, so that different firmware was not needed for
different variations of a keyboard.
