# Key(ID)

base classes — `bpy_struct`, `ID`

class `bpy.types.``Key`(ID)

  Shape keys data-block containing different shapes of geometric data-blocks

  `animation_data`

    Animation data for this data-block

    Type: | `AnimData`, (readonly)

  `eval_time`

    Evaluation time for absolute shape keys

    Type: | float in [0, 1.04857e+06], default 0.0

  `key_blocks`

    Shape keys

    Type: | `bpy_prop_collection` of `ShapeKey`, (readonly)

  `reference_key`

    Type: | `ShapeKey`, (readonly, never None)

  `use_relative`

    Make shape keys relative, otherwise play through shapes as a sequence using the evaluation time

    Type: | boolean, default False

  `user`

    Data-block using these shape keys

    Type: | `ID`, (readonly, never None)

  classmethod `bl_rna_get_subclass`(id, default=None)

    Parameters: | id (string) – The RNA type identifier.
    Returns: | The RNA type or default when not found.
    Return type: | `bpy.types.Struct` subclass

  classmethod `bl_rna_get_subclass_py`(id, default=None)

    Parameters: | id (string) – The RNA type identifier.
    Returns: | The class or default when not found.
    Return type: | type
