These constants are defined in defines.lua and can be used in Lua scripts for hotkey registration, key state checks, and automation.

| VK Name | Value | Key/Description |
|---|---|---|
| VK_OEM_PLUS | 187 | + |
| VK_OEM_COMMA | 188 | , |
| VK_ORM_MINUS | 189 | - |
| VK_OEM_PERIOD | 190 | . |
| VK_OEM_1 | 186 | ü |
| VK_OEM_2 | 191 | # |
| VK_OEM_3 | 192 | ö |
| VK_OEM_4 | 219 | ß |
| VK_OEM_5 | 220 | ^ (left of 1, below ESC) |
| VK_OEM_6 | 221 | ´ (between ß and BACKSPACE) |
| VK_OEM_7 | 222 | ä |
| VK_OEM_102 | 226 | < (between Y and LEFT SHIFT) |
Note: For these keys, use the numeric value in Cheat Engine scripts.
How to Find Other Key Codes[edit]
If you need to find the VK code for a key not listed here, use Nirsoft Keyboard State View to identify the key code.
Usage Example[edit]
-- Register a hotkey for F2
local hk = createHotkey(function() print("F2 pressed!") end, VK_F2)
-- Check if the left shift key is pressed
if isKeyPressed(VK_LSHIFT) then
print("Left Shift is pressed")
end
