Availability
Flash MX 2004.
Usage
timeline.insertBlankKeyframe([frameNumIndex])
Parameters
A zero-based index that specifies the frame at which to insert the keyframe.
frameNumIndex
If you omit , the method uses the current playhead frame number. This
frameNumIndex
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

different from frame number values):

The following example inserts a blank keyframe at the currently selected frame (or playhead
location if no frame is selected):
fl.getDocumentDOM().getTimeline().insertBlankKeyframe();
