## Remarks

Shader keywords determine which shader variants Unity uses. You can use a `GlobalKeyword` to enable, disable, or check the state of a **global** shader keyword. For information on working with [local shader keywords](/engine/6000.0/script-reference/unityengine/rendering/localkeyword.md) and global shader keywords and how they interact, see [Using shader keywords with C# scripts](/engine/6000.0/manual/materials-and-shaders/shaders/writing-custom/shader-writing/sl-multiple-program-variants/shader-keywords-scripts.md).

To set the state of a global shader keyword, use [Shader.SetKeyword](/engine/6000.0/script-reference/unityengine/shader/setkeyword.md), [Shader.EnableKeyword](/engine/6000.0/script-reference/unityengine/shader/enablekeyword.md), or [Shader.DisableKeyword](/engine/6000.0/script-reference/unityengine/shader/disablekeyword.md). To get all the global shader keywords that exist, use [Shader.globalKeywords](/engine/6000.0/script-reference/unityengine/shader/globalkeywords.md). To get all the global shader keywords that are enabled, use [Shader.enabledGlobalKeywords](/engine/6000.0/script-reference/unityengine/shader/enabledglobalkeywords.md).

In addition to this, you can also enable or disable a local or global keyword with a `CommandBuffer`. To do this, use [CommandBuffer.SetKeyword](/engine/6000.0/script-reference/unityengine/rendering/commandbuffer/setkeyword.md), [CommandBuffer.EnableKeyword](/engine/6000.0/script-reference/unityengine/rendering/commandbuffer/enablekeyword.md), or [CommandBuffer.DisableKeyword](/engine/6000.0/script-reference/unityengine/rendering/commandbuffer/disablekeyword.md).
