Regular keys break is_pressed on Mac

[mqw]

On my Mac keyboard.is_pressed('escape') works, keyboard.is_pressed('f') does not.

  File "/opt/homebrew/lib/python3.11/site-packages/keyboard/__init__.py", line 324, in key_to_scan_codes
    raise ValueError('Key {} is not mapped to any known key.'.format(repr(key)), e)
ValueError: ("Key 'f' is not mapped to any known key.", ValueError('Unrecognized character: f'))

Digging through code I have found that:

print(keyboard._os_keyboard.key_controller.key_map.non_layout_keys)
print(keyboard._os_keyboard.key_controller.key_map.layout_specific_keys)

prints

{36: 'enter', 48: 'tab', 49: 'space', 51: 'delete', 53: 'esc', 55: 'command', 56: 'shift', 57: 'caps lock', 58: 'alt', 59: 'ctrl', 60: 'right shift', 61: 'right option', 62: 'right ctrl', 63: 'ƒ', 64: 'f17', 72: 'volume up', 73: 'volume down', 74: 'mute', 79: 'f18', 80: 'f19', 90: 'f20', 96: 'f5', 97: 'f6', 98: 'f7', 99: 'f3', 100: 'f8', 101: 'f9', 103: 'f11', 105: 'f13', 106: 'f16', 107: 'f14', 109: 'f10', 111: 'f12', 113: 'f15', 114: 'help', 115: 'home', 116: 'page up', 117: 'forward delete', 118: 'f4', 119: 'end', 120: 'f2', 121: 'page down', 122: 'f1', 123: 'left', 124: 'right', 125: 'down', 126: 'up'}

The latter dicts values are not set in KeyMap class __init__

for key_code in range(0, 128):
  non_shifted_char = UniChar4()
  shifted_char = UniChar4()
  keys_down = ctypes.c_uint32()
  char_count = UniCharCount()

I have tried just filling the constructor parameters, but it is not sufficient - it does prevent the error, but keyboard.is_pressed('f') still does not work.

I got the same error, manage to fix by adding the 'f' key in the class KeyMap from file: keyboard/_darwinkeyboard.py

the mapping is use following this link: https://stackoverflow.com/questions/3202629/where-can-i-find-a-list-of-mac-virtual-key-codes/16125341#16125341

as the result, you should add to the mapping for 'f' key:
0x03: 'f',
