Even though the animation of relative and absolute shape keys is quite different, there are a few things worth to be noted, valid for both types:
[[File:Doc-26-Manual-Animation-Techs-ShapeKeys-PanelAnimated.png|thumb|300px|right|A {{Literal|Shape Keys}} panel with two animated shape keys.]]
*As nearly every animation in Blender, it is based on keyframing and F-curves.
*As the {{Literal|Shape Keys}} datablock can become an {{Literal|KeyAction}}, you can also use [[Doc:2.6/Manual/Animation/Editors/DopeSheet/ShapeKey|shape keyactions]] and the [[Doc:2.6/Manual/Animation/Editors/NLA|NLA editor]] to animate your shapes.
*And obviously, you can use all "indirect" techniques affecting/controlling F-curves, like e.g. [[Doc:2.6/Manual/Animation/Basics/Drivers|drivers]] – for example, to animate the muscles of your character automatically from its armature’s bones…

Each shape key, except "Basis", creates an animation channel.

{{Warning/Important}}Note that:
*The first created shape key is special. As its name (<code>Basis</code>) states it, it don't have own F-curve and channel.
*You cannot add shape keys from the {{Literal|Graph Editor}} (only the keyframes on exist ones).
*A keyframes for the shape keys can be created at any frame.
*Consequently, shape keys are ''always'' added with {{Literal|Shape Keys}} panel in {{Literal|Object Data}} context of {{Literal|Properties}} window.
*You add relative or absolute shape keys exactly the same way – as said above, you can switch between both behaviors to your liking.

==Animating Relative Shape Keys ==

The basic key idea behind relative shape keys animation is animating {{Literal|Value}} setting which are the ''influence'' of each key and simply defines when and to what extent a key affects the resulting shape. This implies that several shape keys can affect an object at the same time (unlike with absolute keys).

The <code>Basis</code> key defines the (default) “rest” state, when all other keys have a null influence. This is the only key which is '''not animatable'''.

All other keys have an influence that are presented '''{{Literal|Value}}''' option in the {{Literal|Shape Keys}} panel — the standard range is <code>[0.0, 1.0]</code> (from null to full influence), but you can have higher or lower values, which sets {{Literal|Min}} and {{Literal|Max}} settings of {{Literal|Range}} option, giving “over-deformed” or “reversed-deformed” results. This influence is animatable by standart keyframing technique and through a F curve, one for each key (except the <code>Basis</code> one…).

For keyframing animating a shape key with {{Literal|Shape Keys}} panel:
# Go to the first frame '''"0"''' on {{Literal|Timeline}}.
# Select a need shape key in {{Literal|Shape Keys}} panel.
# Click {{Shortcut|rmb}} on its {{Literal|Value}} option and select {{Literal|Insert Keyframe}} from drop-down list.
# Go to a need frame on Timeline where you want this shape is gained full or defined other influence.
# Define a need influence amount for this shape key (in range {{Literal|Min}} and {{Literal|Max}} settings of {{Literal|Range}} option).
# Click {{Shortcut|rmb}} on its {{Literal|Value}} option and select {{Literal|Insert Keyframe}} from drop-down list.

Then, you may to play this shape key animation with {{Shortcut|alt|a}}.

{{Warning/Important}}Note that:
*It seems that Blender automatically detects vertices that do not change at all between a shape key and its basis, and always gives them a null influence (i.e. they will never affect the resulting shape). For simple cases, this avoid you the need of defining and using the “blending” vertex groups (see also [[Doc:2.6/Manual/Animation/Techs/Shape/Shape Keys/Examples|examples]]).
*You can control which vertices are affected (and to what extent) by a given shape key, using vertex groups (see more about [[Doc:2.6/Manual/Animation/Techs/Shape/Shape Keys/Editing|Vertex Group]] setting of {{Literal|Blend}} option in {{Literal|Shape Keys}} panel for relative shape keys).
*For a given key, you can chose a different basis shape than the default <code>Basis</code> one (again, see about the [[Doc:2.6/Manual/Animation/Techs/Shape/Shape Keys/Editing|Shape used a relative key]]setting of {{Literal|Blend}} option in {{Literal|Shape Keys}} panel for relative shape keys). The vertex group influence control might be most useful in this case!
*You can also to animate {{Literal|Min}} and {{Literal|Max}} settings of {{Literal|Range}} option for several purposes.

For editing the exists animation you can:
* Using similar way above with {{Literal|Timeline}} and {{Literal|Shape Keys}} panel for insert another keyframes on another frames on Timeline or remove/replace exists keyframed values for animated shape key.
* Editing already keyframed shape keys F-curves in {{Literal|Graph Editor}}.{{clr}}
[[File:Doc-26-Manual-Animation-Techs-ShapeKeys-GraphEditor.png|thumb|300px|right|A {{Literal|Graph Editor}} window with two shape keys.]] {{clr}}
* Editing timing shape keyframes in {{Literal|Shape Key Editor}} mode of {{Literal|Dope Sheet Editor}}. The {{Literal|Shape Key Editor}} mode is intended only for animating the relative shape keys.{{clr}}
[[File:Doc-26-Manual-Animation-Techs-ShapeKeys-DopeSheetShapeKeyEditor.png|thumb|500px|center|A {{Literal|Dope Sheet Editor}} window in {{Literal|Shape Key Editor}} mode, with two shape keys.]] {{clr}}
* Combining, timing and synchronization {{Literal|KeyActions}} as any actions in {{Literal|NLA Editor}}.

==Animating Absolute Shape Keys ==
[[File:Doc-26-Manual-Animation-Techs-ShapeKeys-GraphEditorAbsolute.png|thumb|300px|right|A {{Literal|Graph Editor}} window with absolute shape keys animated F-curves.]]
Animating Absolute Shape Keys very similar with animation Relative ones, except:
* There are keyframed only {{Literal|Evaluation Time}} and {{Literal|Slurph}} options. You can not change shape key influence values.
* The {{Literal|Shape Key Editor}} mode isn't using for for animating the absolute shape keys.
{{clr}}

==Using Pose markers with Shape Keys animating==
Animated shape key can be signed as a pose with ''pose'' marker in {{Literal|Shape Key Editor}} mode of {{Literal|Dope Sheet Editor}}. This allows to work with shape keys as poses and gives some additional selection and navigation tools.

See more details about pose markers [[Doc:2.6/Manual/Animation/Techs/Armatures|here]].
