# Keys

note

Here you can find information about key input constants used by [GetPlayerKeys](https://omp.itsneufox.com/docs/scripting/functions/GetPlayerKeys) and [OnPlayerKeyStateChange](https://omp.itsneufox.com/docs/scripting/callbacks/OnPlayerKeyStateChange).

SA-MP uses bitmasking to determine which keys are pressed and which are not. Here's an article on bitmasking: [https://en.wikipedia.org/wiki/Mask\_(computing)](https://en.wikipedia.org/wiki/Mask_\(computing\))

**(1):** Key not defined in SA:MP includes. You must

```c
#define KEY_AIM KEY_HANDBRAKE
```

or use KEY\_HANDBRAKE.

**(2):** This key can not be detected when the player is in [spectator mode](https://omp.itsneufox.com/docs/scripting/functions/TogglePlayerSpectating).

**(3):** GROUP\_CONTROL\_FWD cannot be detected in SA-MP, as it used internally to enter vehicles as passenger. However, the gametext definition still exists.

**(4):** If the key number "262144" does not work, just use key number "2".

**(5):** Only detected when "JOYPAD" configuration is selected for controller.

**(6)** Embedding codes only work for [client messages](https://omp.itsneufox.com/docs/scripting/functions/SendClientMessage), [textdraws](https://omp.itsneufox.com/docs/scripting/functions/TextDrawCreate) and [gametexts](https://omp.itsneufox.com/docs/scripting/functions/GameTextForPlayer).

**(7)** If a player sits in a vehicle with no radio stations (Cop cars, RC vehicles), both R and H will return "262144" for their session. But if they don't, pressing H / Caps Lock in vehicle only returns "2", while R button returns "262144".
