timeline.insertBlankKeyframe()

#### Availability

Flash MX 2004.

#### Usage

timeline.insertBlankKeyframe(\[frameNumIndex\])

#### Parameters

frameNumIndex A zero-based index that specifies the frame at which to insert the keyframe. If you omit
frameNumIndex, the method uses the current playhead frame number. This parameter is optional.
If the specified or selected frame is a regular frame, the keyframe is inserted at the frame. For example, if you have a span of 10 frames numbered 1-10 and you select Frame 5, this method makes Frame 5 a blank keyframe, and the length of the frame span is still 10 frames. If Frame 5 is selected and is a keyframe with a regular frame next to it, this method inserts a blank keyframe at Frame 6. If Frame 5 is a keyframe and the frame next to it is already a keyframe, no keyframe is inserted but the playhead moves to Frame 6.

#### Returns

Nothing.

#### Description

Method; inserts a blank keyframe at the specified frame index; if the index is not specified, the method inserts the blank keyframe by using the playhead/selection. See also timeline.insertKeyframe() (../Timeline_object/timeli29.md).

#### Example

The following example inserts a blank keyframe at Frame 20 (remember that index values are different from frame
number values):

javascript
fl.getDocumentDOM().getTimeline().insertBlankKeyframe(19);

The following example inserts a blank keyframe at the currently selected frame (or playhead location if no frame is selected):

javascript
fl.getDocumentDOM().getTimeline().insertBlankKeyframe();
