The Dope Sheet.

The Dope Sheet gives the animator a birds-eye-view of the keyframes inside the scene.

The Dope Sheet is inspired by classical hand-drawn animation process, in which animators will make use of a chart, showing exactly when each drawing, sound and camera move will occur, and for how long. This is called an exposure sheet or 'dope sheet'. While CG foundations dramatically differ from classical hand-drawn animation, Blender's Dope Sheet inherits a similar directive.

Dope Sheet Modes

Dope Sheet modes.

While the Dope Sheet Mode allows you to edit multiple actions at once, the other ones are dedicated to view and edit specific data-blocks used in different context of animation.

• Dope Sheet

• Action Editor

• Shape Key Editor

• Grease Pencil

• Mask

Main Region

Navigation

As with most editors, you can:

Pan

Pan the view vertically (values) or horizontally (time) with click and drag (MMB).

Zoom

Zoom in and out with the mouse wheel (Wheel).

Scale View

Scale the view vertically or horizontally (Ctrl-MMB).

In addition, you can also use the scrollbars to pan and zoom the view.

Keyframes

The Dope Sheet Editor with object channels.

This area contains keyframes for all visible action channels. As with the other time-based editors, the X axis represents time. The Y axis represents a stack of action channels.

On these channels lay the keyframes, which can show different information:

Gray	Unselected
Yellow	Selected
Diamond	Free Keyframe Handle
Round	Auto-Clamped Keyframe Handle
Circle	Automatic Keyframe Handle
Square	Vector Keyframe Handle
Rhombus	Aligned Keyframe Handle
Various colors	These represent custom keyframe tags set by the user (Key ‣ Keyframe Type)
Gray bar between keys	Held key (the two keyframes are identical)
Green line between keys	Fixed keyframe interpolation (set in Key ‣ Interpolation Mode)
Upwards arrow	Maximum Extreme keyframe (visible if View ‣ Show Curve Extremes are enabled)
Downwards arrow	Minimum Extreme keyframe (visible if View ‣ Show Curve Extremes are enabled)

Selecting Keyframes

Selection tools are available in the Select menu in the header, and the main shortcuts are listed below:

Selecting

Click on a key to select it. Hold Shift to extend the current selection.

Box Selecting

Click and drag to box select multiple keyframes at once. You can hold Shift to extend or Ctrl to subtract from the current selection.

Select Lasso

See Lasso Select.

Select/Deselect All

• To select all keys, press A.

• To deselect all keys, press Alt-A.

• To inverse the selection, press Ctrl-I.

Before/After Current Frame [, ]

Select all to the right or left. Or hold Shift-Ctrl and click on either side of the Playhead.

See the Select menu for a full list of selection tools.

Manipulating Keyframes

Keyframe tools are available in the Key menu in the header, and the main shortcuts listed below:

Moving Keyframes

To move a single keyframe, click and drag on a key. To move multiple keyframes, make sure several keys are selected and press G.

Scaling Keyframes

To scale (stretch) selected keys, press S.

Extending Keyframes

To extend the time between two keys, select all with A, place the Playhead between two keyframes and press E.

See the Key menu for a full list of selection tools.

Channels Region

The Action editor's channels region.

See Channels.

Header

Here you find the menus, a first group of controls related to the editor "mode", a second one concerning the action data-blocks, and a few other tools (like the copy/paste buttons, and snapping type).

View Menu

Handle types.

Show Handles and Interpolation

Instead of displaying all keyframes as diamonds, different icons are used to show the Bézier handle type. When curves use a different interpolation type, a line is shown between keys to highlight that.

See Handles & Interpolation Display.

Extreme markers.

Show Extremes

Detect keys where the curve changes direction based on comparing with the adjacent key values, and display that by changing the keyframe icons to resemble an arrow. A muted version of the icon is used if the curve overshoots the extreme, or for groups with different results for contained curves.

See Graph editor's View Menu.

Markers Menu

Markers are used to denote frames with key points or significant events within an animation. Like with most animation editors, markers are shown at the bottom of the editor.

Markers in animation editor.

There are some options that are exclusive to the Dope Sheet editor:

Sync Markers

Sync Markers with keyframe edits.

Show Pose Markers

Available in Action and Shape Key modes. Shows pose markers owned by the active action instead of the scene ones.

Make Markers Local

Available in Action and Shape Key modes. Converts selected scene markers in pose markers, assigning them to the active action.

For more information and the description of the other marker tools, see Editing Markers.

Key Menu

Keyframe Type R

Sets the Keyframe Types of the selected keyframes.

See F-Curve.

Filters

Only Show Selected

Only include keyframes related to the selected objects and data.

Show Hidden

Include keyframes from objects or bones that are not visible.

Only Show Errors

Only include curves and drivers that are disabled or have errors. Useful for debugging.

F-Curve Name Filter

Fuzzy/Multi-Word name filtering matches word snippets/partial words, instead of having to match everything. It breaks down the search text based on whitespace placement. e.g. "lo ro" will filter all location and rotation, while "lc rt" will not work.

Filter by Type

Filter curves by property type.

Filtering Collection

Select a collection to only show keyframes from objects contained in that collection.

Sort Data-Blocks

Objects data-blocks appear in alphabetical order, so that it is easier to find where they occur (as well as helping to keep the animation of related objects together in the NLA editor for instance).

If you find that your playback speed suffers from this being enabled (it should only really be an issue when working with lots of objects in the scene), you can turn this off.

Summary

Toggles the "Dope Sheet Summary" channel at the top of the Channels Region. This is used to give an overview of all the channels by combining all the actions into one channel.
